Energy is a crucial factor and a capital of a country's resources leading indicator. World's energy focus is shifting towards alternate renewable, cheap and environment-friendly resources that can provide long-term sustainability for survival. Due to the fossil fuels depletion and their ever-growing cost, the need to shift focus towards renewable energy resources has increased a lot. To overcome the above-said problems, there is a need to look for a feasible and robust solution for thermal applications in remote areas. Biomass gasification proved to be one of the most efficient and clean waste-to-energy conversion processes in contrast to direct combustion of agricultural waste. Other than controlled burning of biomass, it can be subjected for different purposes like a thermal, synthesis of ethanol, engine running, and for fuel cell applications. An excessive amount of impurities like char, ash, tar, and particulate matter are making these syngas non-feasible for thermal or engine applications. To overcome the above-stated problem, a downdraft gasifier with cyclone separator and hybrid biomass filter was fabricated using locally available materials in the workshop of the Dept. of Farm Machinery and Power at the University of Agriculture, Faisalabad. Uniform distribution of 2.54-5.08 cm2 sizes of feedstock was used for gasification. Air was used as a gasifying agent. The reactor capacity was 0.19 m3. The values of performance parameters for wood waste and corncobs were recorded as fuel consumption rate (0.002195, 0.002323) kg-s-1, the volume of gas produced (24.56, 26.33) m3, operating time (5480, 5164) s, cleaning unit efficiency (81.79, 79.9) % and gas yield (2.04, 2.19) m³-kg-1.

Objective: To determine the impact of the information seminar on breast cancer awareness among the medical and nursing students of CMH institute of Medical Sciences (CIMS) Multan Pakistan. Study Design: Prospective Comparative Study. Place and Duration of Study: One-day seminar at CMH Institute of Medical Sciences (CIMS) Multan Pakistan. Methodology: A one-day seminar on breast cancer awareness was arranged at CMH Institute of Medical Sciences Multan Pakistan for 3rd and 4th-year MBBS and 3rd-year BSc Nursing students. A total of 137 participants were recruited. Participants were selected by non-probability consecutive sampling. A validated 13-question questionnaire was designed to assess participants' basic knowledge of breast cancer and breast self-examination (BSE). Results: The mean age of participants was 21.27±0.99 years. 30(21.9%) were males and 107(78.1%) were female students. Before the seminar, approximately half of the students were correct about the demographics and presentation of breast cancer which increased to more than 80% in all avenues post-seminar (p<0.001). The most significant improvement was the correct responses regarding the age at which BSE should begin. Its frequency and correct technique pre-seminar were 75(54.7%), 51(37.2%) and 23(16.8%), which in post-seminar were 98(71.5%), 106(77.4%) and 75(54.7%) respectively (p<0.001).

During the study, different control practices, such as host plant resistance, imidacloprid seed treatment combined with the use of blue sticky traps, neem seed kernel extract, the entomopathogenic fungus Beauveria bassiana and synthetic insecticides (acephate and chlorfenapyr), were tested individually and in various combinations for managing thrips (Megalurothrips distalis). A mungbean genotype, 13TM-04, known for its comparative resistance, was chosen for these trials. The treatments, whether applied alone or in various combinations, showed significant differences in efficacy when compared with each other. A combination of treatments viz., imidacloprid seed treatment+ installation of blue sticky traps and chlorfenapyr 360 SC @ 100ml/acre spray was observed to be the most successful against thrips and resulted in maximum yield 1970.1 kg/ha of mungbean. While imidacloprid seed treatment with blue sticky trap installation, alone, did not show distinctive impact on the thrips population as well as on the yield in mungbean. The imidacloprid seeds treatment remained effective up to 38 days after sowing against the thrips. The application of chlorfenapyr and acephate, either individually as sprays or in combination with other control measures, resulted in a notable reduction in the thrips population. For the management of M. distalis in mungbean combination of imidacloprid seed treatment, blue sticky traps installation and chlorfenapyr at 100 ml/acre should be applied. Current studies provide useful information to adopt integrated pest management of thrips at Bhakkar district for the local farmers for better crop yield. [ABSTRACT FROM AUTHOR]

Objective: To detect the resistant pattern of uropathogens and find the association of different factors with the resistance in the Poonch District of Azad Kashmir. Study Design: Cross-sectional analytical study. Place and Duration of Study: Department of Medicine, Shaikh Khalifa Bin Zayed Hospital, Rawalakot, from Mar to Aug 2019. Methodology: Patients having signs and symptoms of urinary tract infection and growth of bacteria on urine culture were included in the study. The antimicrobial susceptibility of the isolates was determined by using the standard, modified Kirby Buer disc diffusion method. Zone sizes were interpreted following Clinical Laboratory Standards Institute (CLSI) 2019 guidelines. Results: 68 culture-positive patients were included in the study, 45 (66%) patients were female. There was a previous history of urinary tract infection in 44 (64.7%) patients, and 52 (76.5%) gave a history of antibiotic use in the last three months. E. coli was the commonest organism isolated, followed by Klebsiella, Proteus and Pseudomonas. All patients were resistant to at least one antibiotic, 48 (72%) isolates were multi-drug resistant. Uropathogens showed the highest resistance to Ampicillin in 67 (98.5%) patients and the lowest resistance to Piperacillin/Tazobactam 2 (3%) patients only. Resistance was significantly higher in patients having a history of recurrent urinary tract infection (p=0.028) and the use of antibiotics in the last three months (p<0.001). Conclusion: Resistance to antimicrobial agents is increasing in community-acquired urinary tract infections. Resistance is significantly higher in patients having a history of recurrent urinary tract infection and the use of antibiotics in the last three months. [ABSTRACT FROM AUTHOR]

Over the years, a crop variety grown on the commercial scale and under different conditions becomes vulnerable to various kinds of issues involving both biotic and abiotic plant stresses, alone or in combinations. This demands their substitution with new and improved genotypes possessing higher productivity and inherent resistance/tolerance against yield-limiting stresses. In this context, this editorial reports the development of a new chickpea kabuli variety "Noor-2019". This cultivar has improved yield potential, dietary elements (proteins, fat, ash), and more importantly, resistance against fusarium wilt and ascochyta blight compared to the existing varieties. The evolution of this strain commenced in 2002-03 cropping season by crossing K-90399 as a female parent with K-52582 as a male parent. The female parent had high yield potential, whereas the male parent had wilt resistance and was developed through introgression breeding using ILWC-126, an accession of Cicer reticulatum. Henceforth, the genetic variability was created to select for high yield and wilt resistant recombinants in subsequent generations. Resultantly, a uniform and high yielding progeny line PCK-09012, later designated as "Noor-2019" was selected and evaluated for yield, agronomy, and insect pests. This cultivar revealed a potential yield of 2882 kg ha-1 in testing phase and outperformed standard checks by producing 78.2%, 13.1%, and 28.8% higher grain yield in station, adaptation and national uniform yield trials, respectively. The plants of Noor-2019 are 60-65cm tall, semi-erect, and medium in canopy spread. Its grains are light brown, ram-headed, medium in size with a 100-seed weight of 25 g. Adoption of this cultivar across different climatic regions of Punjab, and other provinces could contribute in attaining self-sufficiency in local chickpea production as well as plummeting import bill.

Current study was aimed to formulate a nutritious snack bar by incorporating date pit powder (by product) and soy protein isolate in date paste. Date bars were formulated after ingredients optimization and were analyzed for physico-chemical, in-vitro starch and protein digestibility, antioxidants and microbial count. Results showed that date bars are rich source of protein, fiber, carbohydrates and fat with good digestibility properties. Date pit powder and soy protein isolate incorporation enhanced the total antioxidants and DPPH activity in soy date bars however, decreasing trend was observed in total antioxidants and inhibition of DPPH radical activity during 90 days of storage. Based on the results, it has been suggested that date bars may be considered as a source to meet the energy requirements of health-conscious consumers. Moreover, date pit powder and soy protein isolate can be used as nutraceutical in different functional foods as a valuable nourishment source for target population. [ABSTRACT FROM AUTHOR]

Objective: To discern the relationship of height and weight with body composition in healthy attendants of cancer patients. Study Design: Cross-sectional study. Place and Duration of Study: Combined Military Hospital, Rawalpindi Pakistan, from Oct to Dec 2022. Methodology: A total of 226 healthy adults aged 19-47 years having similar daily physical activity levels were included. The body composition of study participants was evaluated using a bioelectric impedance analysis (BIA) machine. The weight of all participants was recorded with the help of a weighing machine. The participants' height was measured using a Harp enden Stadiometer and recorded. Results: Our study showed that weight had a significant positive correlation with body fat mass (rs value=0.83), skeletal muscle mass (rs value=0.763), total body water (rs value=0.704), fat-free mass (rs value=0.75) and per cent body fat (rs value 0.716). On the other hand, height had a negative but non-significant association with fat mass (rs value= 0.025) and a negative significant association with per cent body fat (rs value=-0.16). Height had a positive and significant association with fat-free mass (rs value=0.553), total body water (rs value=0.501) and skeletal muscle mass (rs value=0.505). Conclusion: Weight, if used alone, is not a good indicator of obesity or emaciation, and height has a negative association with fat mass. [ABSTRACT FROM AUTHOR]

Objective: To validate a clinical scoring system for defining the severity of ailment that will assist in developing strategies for management prioritisation. Study Design: Cross-sectional analytical study. Place and Duration of Study: Paediatric Department, Combined Military Hospital Lahore, Pakistan, form Jan 2020 to Jul 2021. Methodology: The paediatric patients who reported to the Medical Reception Centre and were admitted to an Inpatient Facility were enrolled. Demographic profile, temperature, oxygen saturation, pulse, respiratory rate, seizures, and sensorium labelled as "TOPRS" score was recorded with "0 - Normal" and "1 - Abnormal" and scores calculated for each patient with the incorporation of systemic inflammatory response and advanced paediatric life support criteria. Results: A total of 300 paediatric patients with an age range of 1-18 years (mean: 3.86±5.43) were included. Of 300 patients, 237(79%) were discharged after improvement, and the mortality rate was 63(21%). A significant association with the mortality rate was deciphered with temperature, oxygen saturation, and respiratory rate variables. In contrast, pulse rate, sensorium, and seizures were concluded to have an insignificant association. Score "0" mortality was associated with the 4.4% mortality, whereas score "5" enumerated an 80% death rate. Conclusion: The TOPRS clinical scoring system has significant value in the diagnosis of mortality and morbidity of paediatric patients and, hence, can assist in early recognition and triage of patients, consequently aiding in the provision of prioriti sation protocols and management in a befitting manner.

Objectives: To determine the diagnostic accuracy of the pSOFA score in predicting mortality in critically ill pediatric patients. Study Design: Cross-sectional validation study. Place and Duration of Study: Department of Paediatrics, Pak-Emirates Military Hospital, Rawalpindi Pakistan, Aug 2021 to Feb 2022. Methodology: We studied 76 critically ill paediatric patients. All patients underwent pSOFA scoring on admission and then at 72 hours post-admission and were followed up till discharge or till mortality occurred. A pSOFA score of >10 was considered a high mortality risk. The two-by-two table was constructed to calculate the sensitivity, specificity and diagnostic accuracy of the pSOFA score in predicting the occurrence of death. Results: The pSOFA score had a sensitivity of 88.9% at Day-0, which improved to 100% by Day-7 in predicting whether mortality occurred. The specificity was 80.6% on Day-0 and 97.0% on Day-7. The diagnostic accuracy of pSOFA in predicting mortality was 81.6% when performed on the day of admission, which increased to 90.8% when calculated on Day 3 and was the highest on Day-7 when it was 97.4%. Conclusion: The pSOFA score has good diagnostic accuracy in predicting the occurrence of mortality in paediatric patients admitted to intensive care, which increases as the length of stay increases.

Analytical characterization of pure, blended watermelon (Citrulluslanatus) oil and impact of blending on oxidative stability was investigated. Watermelon oil was added with mango (Mangiferaindica L.) kernel oil at four different concentrations, 5, 10, 15 and 20% (B1, B2, B3 and B4) and referenced with a control (100% watermelon oil).All the blends were stored in transparent PET bottles at ambient temperature (25-28°C) for 3 months; storage stability was assessed at the interval of 1 month. Free fatty acid, unsaponifiable matter, saponification value, refractive index and iodine value of watermelon seed oil and mango kernel oil was, 1.38%, 0.34%; 0.71%, 1.68%; 198, 193; 1.468, 1.457; 107.51, 54.62; respectively. The α tocopherol content of watermelon oil, mango kernel oil, B1, B2, B3 and B4 was 127.49, 205.44, 135.24, 144.52, 156.81 and 169.34 mg/kg. δ tocopherol in watermelon oil, mango kernel oil, B1, B2, B3 and B4 was 55.26, 34.81, 53.64, 51.27, 50.14 and 48.23 mg/kg. Concentration of linoleic acid decreased from 50.78% to 30.17% when 40% mango kernel oil was added to watermelon oil. Oleic acid increased from 22.89% in watermelon oil to 25.19%, 28.84% and 30.64% in B1, B2, B3 and B4. The increase in peroxide value of watermelon oil, B1, B2, B3 and B4 was 10.07, 9.56, 7.62, 5.17 and 2.87 (meqO2/kg) in a time dependent manner. Induction period of pure watermelon oil was less than mango kernel oil and blends. These results suggest that chemical characteristics and oxidative stability of pure watermelon oil can be improved by blending with mango kernel oil. [ABSTRACT FROM AUTHOR]

Studies were conducted in the Grain Research Training and Storage Management Cell (GRTMC), Department of Agri- Entomology, University of Agriculture Faisalabad, to evaluate the effect of Spinosad (0.25%, 0.50%, 0.75% and 1.0%) at different doses with different exposure times against Tribolium castaneum. Spinosad at 1%, 0.75%, 0.50% and 0.25% concentrations killed 61.85%, 55.56%, 45.93% and 32.59% Tribolium castaneum adults respectively which were statistically different (P=0.05) than the percent kill of the test insect in the control. The toxicity of spinosad to the test insect was also dose dependent, the higher the concentration, the significantly more mortality of the insect. Exposure of the test insect to spinosad for different time intervals (24, 48 & 72 hours) resulted into different percent mortality of T. castaneum. The percent mortality of the insect after 72hours (51.33%) exposure was significantly different from the percent mortality after 48hours (40.89%) and 24hours (25.33%) exposure. The interaction effect of 1% spinosad and 72 hours exposure gave 75.55% kill, which was significantly (P=0.05) more than the percent kill of the other concentrations & exposure time except the interaction effect at 0.75% spinosad exposed for 72 hours. The population build-up of T. castaneum after exposure to Spinosad at different concentrations and different exposure time was significantly lower than that in the control. The negative effect of the chemical on the population build up of T. castaneum was dose and exposure time dependent. [ABSTRACT FROM AUTHOR]

A field study was conducted to evaluate one combination of seed treatment with imidacloprid (Confidor 70 WS) and spray with detergent and for insecticide sprays: imidacloprid (Confidor 20% SL), acetamiprid (Acelan 20% SL), thiomethoxam (Actara 25 WG) and acephate (Commando 75 SP), against sucking insect pests on mungbean, Vigna radiata (L.) at Arid Zone Research Institute (AZRI), Bhakkar during 2012. All the treatments showed a significant difference with one another, regarding their effectiveness. The application of insecticide sprays immediately enhanced the mortality of the pests, whereas, the effect of seed-treatment and detergent did not show distinctive effect on the pests' population. Imidacloprid and thiomethoxam resulted in a maximum mortality of the jassid, followed by acetamiprid. While in case of whitefly, imidacloprid was the most effective and resulted in a minimum population followed by acetamiprid. Acephate resulted in the maximum control of thrips and was found the most effective insecticide, followed by acetamiprid. [ABSTRACT FROM AUTHOR]

The main purpose of the study was to determine the suitable selection method for genetic improvement in chickpea. The current investigation was conducted at the research area of the Arid Zone Research Institute, Bhakkar, Punjab, Pakistan. Twelve chickpea genotypes were sown in RCBD following three replicates. Data regarding primary & secondary per plant, days for maturity, plant height as well as potential yield were recorded. The measured data were analyzed to principal component analysis (PCA), correlation, and path coefficient analysis. Analysis of variants revealed good variation among the accessions for the data recorded traits. Principal coefficient analysis differentiates all the traits into six PCs. Two components expressed more than one Eigenvalue which collectively contributed 80.12% towards the genetic variation. High positive loadings were expressed by the secondary branches per plant and pods per plant in all components. Path analysis revealed that secondary branches/plants expressed the highest direct positive effect (0.872) grain yield followed by the pods per plant (0.623). Analysis of correlation coefficient also confirmed the highest significant contribution of secondary branches per plant (91.57%) followed by pods (78.12%) and each plant's primary branches (64%). It was proved from the current experiment that Plants with secondary branches as well as pods may be focused on while assessing meaningful selection criteria for genetic improvement in chickpea.

Objective: To investigate the dependency on feeding gastrostomy tubes in patients with head and neck cancers treated with radiotherapy alone or concurrent chemo-radiotherapy. Study Design: Retrospective longitudinal study. Place and Duration of Study: Combined Military Hospital, Rawalpindi and Shaukat Khanum Hospital, Peshawar Pakistan, from Jan and Jul 2022. Methodology: A total of 115 patients with head and neck cancers having no baseline dysphagia and having gastrostomy tubes were included. All had received an equivalent of 60 greys in 30 fractions or more of radiotherapy. Their swallowing was evaluated weekly during radiotherapy and then every 4-6 weeks on post-treatment follow-up. The total time duration of patient dependency on feeding gastrostomy tube after treatment completion was noted for each head and neck cancer subsite. Results: Of a total of 115 patients, 49(43%) of the patients had nasopharyngeal cancers, 22(19%) had laryngeal, 29(24%) oral cavity, 7(6%) hypopharyngeal and 9(8%) had cervical esophageal cancers. Proportion retaining gastrostomy tube for more than six months of treatment was 8.7% (median duration of retention was five months) with hypopharyngeal, nasopharyngeal, oral cavity, and laryngeal cancer were 14%, 9%, 9% and 5%, respectively. Conclusion: The proportion of patients with head and neck cancers requiring more than six months of a gastrostomy tube is 5-14%. Baseline assessment of swallowing and nutrition and prophylactic feeding gastrostomy can avoid treatment interruptions. Longer duration of retention of a gastrostomy tube is associated with poor quality of life in head and neck cancer patients receiving radiation or concurrent chemo-radiation. [ABSTRACT FROM AUTHOR]

In addition, patients using Anthracyclinebased chemotherapy and taking chemotherapy for more than three months were more at risk of developing adverse effects. [ABSTRACT FROM AUTHOR]

To improve yield and shelf life of stock can enhance economic value to flowers growers globally. A study was conducted to evaluate the efficacy of various bio-stimulants on yield and quality of stock. Three cultivars of stock, viz. 'Cheerful White', 'Iron Rose' and 'Iron White' foliarly sprayed by bio-stimulants (Isabion and Tecamin Max) with three different concentrations (1 ppm, 3 ppm, and 5 ppm) with the different number of sprays (1, 2, or 3 sprays). The first spray was applied after one month of transplanting, while the other two were applied at fortnight intervals after the first spray. Fisher's Analysis of variance revealed that Isabion at 1 ppm as 1 spray, 3 ppm as 3 sprays, and 5 ppm as 3 sprays produced the highest plant height for three cultivars of stock. 'Cheerful White' had the highest stem length when plants were sprayed once at 1 ppm Isabion. Among cultivars, 'Iron Rose', produced highest leaf area (42.8 cm2) with 3 ppm Isabion application, when sprayed only one time. Among the number of sprays, plants sprayed three times with Isabion produced the thickest stem diameter followed by 2 and 1 sprays. 'Cheerful White' had maximum leaf total chlorophyll contents, followed by 'Iron White' and 'Iron Rose' (69.1 SPAD and 68.8 SPAD, respectively). Among the number of sprays, plants sprayed three times had the longest vase life. Cheerful White proved early cultivar of stock while Iron White were late cultivars when grown in agro-climatic conditions of Faisalabad. Tecamoin Mix is recommended biostimulant for quality production of Mathiola incoma L. rather than isabion. [ABSTRACT FROM AUTHOR]

Purple blotch disease is exerting a severe threat on onion production. The current study was conducted for screening of accessions against purple blotch disease and determining the source of resistance against Purple blotch disease of onion caused by Alternaria porri. Potential of 50 onion accessions was evaluated against A. porri during 2017 and 2018 under field conditions. After that effect of some fungicides and plant extracts was determined for disease suppression on a susceptible variety of onion. During both years of study, eight accessions (Phulkara, Texas Early, Cylon, Sunset, Red Gystal, Rubi F1, Red Flame, ON-14133) exhibited resistant response with minimum percent disease index (PDI) which ranged between 5-10%, followed by Mirpurkhas, Nasarpuri, HON-1069, Pania, Rubi F2, GSL-132, Red Moon, PK-1032, F-1122, Red Imposta, Early Red, Desi Large and Vrio-4 which showed moderately resistant response to A.porri with PDI of 11-20%, whereas, the four accession including Golden Arab, Desired, Sultan F1 and Red Nasik expressed Moderately resistant response with PDI of 21-40%. Moreover, six accessions (Yellow Gystal, Vrio-9, Vrio-5, Vrio-4, Vrio-1, and Vrio-3) expressed susceptible response with high value of PDI 41-60% whereas; nine accessions (CBS-130, ON-14121, Pink Panther, Vrio-7, Vrio-3, F1 Zeus, SE-16, Vrio-8 and Marvi) showed maximum value (Above 60%) of PDI and expressed highly susceptible response to A.porri. Among fungicides and botanical extracts, Chlorostrobin and Azadirachta indica extract expressed significant reduction in disease severity. It was concluded that out of 50, only eight accessions were resistant which might be grown successfully for higher crop production. Moreover, use of Chlostrobin and extract of Azadirachta indica may be used for disease management. [ABSTRACT FROM AUTHOR]

Weeds are serious pests in rice sown under direct-seeded rice (DSR) technology. Herbicide-based weed management is becoming increasingly popular, but there is a dire need to choose appropriate herbicides and their effective dose for controlling weeds in DSR fields. A field trial was conducted to appraise the comparative efficacy of three post-emergent herbicides applied at different doses [Clover 20% EC (bispyribac sodium) at 39.54, 59.30, and 79.07 g a.i. ha-1, Pyranex Gold 30% WDG (bispyribac sodium + bensulfuron methyl) at 74.13, 111.20, and 148.26 g a.i. ha-1, and Puma Super 7.5% EW (fenoxaprop-p-ethyl) at 46.33 and 92.66 g a.i. ha-1] at 20 days after sowing (DAS) for weed control and paddy yield performance under DSR system. A weedy check was retained as control. Results revealed that Clover and Pyranex Gold applied at either dose significantly (p≤0.05) reduced the population and growth of Cyperus iria (90-97% weed density and 93-97% weed dry biomass) and Echinochloa colona (94-97% weed density and weed dry biomass) weeds over control, while Puma Super proved efficient in suppressing Leptochloa chinensis and Echinochloa colona weeds. Among all the tested treatments, application of Puma Super at 92.66 g a.i. ha-1 furnished the highest number of tillers (137.3 in 2014 and 141.3 in 2015), grains panicle-1 (77 in 2014 and 79 in 2015), final paddy yield (1983.8 and 1570 kg ha-1 in 2014 and 2015, respectively), and net economic returns (Rs. 95915 ha-1), followed by the use of Puma Super at 46.33 g a.i. ha-1 which offered the next best economic benefits (Rs. 81906 ha-1). Thus, applying Puma Super at 92.66 g a.i. ha-1 is appeared viable approach to control grassy weed flora and ensure higher paddy yield with higher economic returns when rice is sown under DSR technology.

1H and 13C-NMR spectra indicate that naphthalene portion of 1,4-bis-(chloromethyl)- naphthalene was slightly twisted due to C8 – H---Cl* bonding. The electrons distribution on magnetically equivalent carbons became uneven that is why ten carbon peaks instead of five pairs of magnetically equivalent carbons had appeared in 13C-NMR spectra. Due to C8 – H --- Cl* bonding, extension and contraction in bond lengths from their normal positions had occurred. Similar case was with 1H-NMR of the said compound. The molecule also showed antifungal and antibacterial properties. [ABSTRACT FROM AUTHOR]

Tunnel farming is getting popular in the farmer's community of Pakistan due to the possibility of growing off-season vegetable crops with high yield in a controlled environment. In the current study, the development and validation of IoT system consisting of monitoring and control units were carried out for controlling the environmental factors in tunnel farming. Three tunnels were set for monitoring the environmental factors using temperature, humidity and soil moisture sensors. Two of three tunnels were fit with control units of exhaust fans and air heaters and a water pump for controlling the temperature and soil moisture. During the testing and validation of the system, temperatures recorded through DHT-21 sensor and thermometer in tunnel 1, 2 and 3 had strong correlations of 0.9986, 0.998 and 0.9978 respectively. Similarly, strong correlations of 0.9987, 0.9994 and 0.998 were found for RH (%) measured through DHT-21 sensor and RH meter for tunnel 1, 2 and 3 respectively. For soil moisture measurement, similar correlations were observed for resistive soil moisture sensor and oven dry method. It was explored that an increase in temperature through an air heater decreases the RH in tunnel 1 and 2 compared to tunnel 3 which has higher RH because it was not installed with air heater and exhaust fan. System controlled the temperature and soil moisture within adjusted limits of 22-27 °C, 17-23 % for tunnel 1 and 19-22 °C, and 19-23 % for tunnel 2. [ABSTRACT FROM AUTHOR]

Objective: To assess the predictors associated with mortality within 8 weeks in patients undergoing endoscopic N-butyl-2-cyanoacrylate treatment. Study Design: Prospective comparative study. Place and Duration of Study: Department of Gastroenterology, Services Institute of Medical Sciences, Lahore Pakistan, from Mar 2018 to Mar 2019. Methodology: A total of 106 patients of gastric variceal bleed were enrolled in the study. Tissue glue was injected into the varix endoscopically and mortality within 8 weeks after endoscopic intervention was noted. Results: Among the enrolled patients, 65 (61.3%) were male and 41(38.7%) were female. Mortality was noted in 19 (17.9%) patients within 8 weeks after endoscopic therapy. Chi-square analysis showed creatinine >1.5, Child Pugh score >9, MELD score >18, re-bleeding within 7 days, low blood pressure <90/60 at presentation and hepatic encephalopathy as significant predictors of mortality (p<0.005). Conclusion: Cirrhotic patients undergoing endoscopic injection of gastric varix with N-butyl 2-cyanoacrylate after gastric variceal bleed have high risk of death within 8 weeks.

Objective: To determine the relationship of baseline quantitative BCR ABL1 gene percentage and therapeutic response i.e. Early Molecular Response (EMR) at 3 months with first generation Tyrosine kinase inhibitors (Imatinib) in patients with Chronic Myeloid Leukemia (CML) in chronic phase (CP) Study Design: Prospective observational study. Place and Duration of Study: Combined Military Hospital, Rawalpindi, Pakistan, and Armed Forces Institute of Pathology Rawalpindi, Pakistan from Oct 2017 to Oct 2019. Methodology: One hundred and seventy patients, 18 years of age or older with newly diagnosed Chronic Myeloid Leukemia (CML) in chronic phase (CP) with quantitative baseline BCR-ABL (IS) transcript were included in the study. All enrolled patients were placed on Imatinib therapy (400 mg/day) and Reverse transcription polymerase chain reaction (RT-PCR) for BCR ABL transcript was repeated at 3 months to document EMR (BCR-ABL (IS) <10%). Patients who were in accelerated/blast phase, or already taking any Tyrosine Kinase Inhibitors (TKI) or chemotherapy were excluded from the study Results: In our study 101 (59.4%) patients achieved early molecular response. Out of these 80 (70.8%) patients with BCR-ABL<50% at baseline value showed early molecular response. However, only 21 (36.8%) with BCRABL >50% at baseline achieved early molecular response (p-value <0.001). Conclusion: A significant number of patients achieved early molecular response with Imatinib therapy that had BCR ABL below 50%, however those with baseline BCR ABL >50%, the rate of EMR was comparatively lower.
