Objective: To evaluate the infrazygomatic crest (IZC) bone and develop guidelines for the optimum placement of orthodontic miniscrew implants (OMSIs) along the distobuccal root of the permanent maxillary first molar. Methods: Bone thickness of the IZC region of 50 young adults (25 males and 25 females) aged 18-30 years were evaluated using cone-beam computed tomography images. The infrazygomatic bone thickness along the distobuccal root of the permanent maxillary first molar was assessed at various insertion angles (40° to 75° i.r.t the maxillary occlusal plane) with an increment of 5°. Student’s t-test was used to compare the IZC bone thickness and height at the orthodontic miniscrew insertion site for males and females on the right and left sides. Results: The bone thickness of the IZC region above the distobuccal root of the permanent maxillary first molar was estimated between 4.39±0.25 mm and 9.03±0.45 mm for insertion angles from 40° to 75° to the maxillary occlusal plane. The corresponding OMSI insertion heights were 17.71±0.61 mm to 13.69±0.75 mm, respectively, above the maxillary occlusal plane. There were statistically significant gender and side-wise variations in bone thickness at the IZC area and insertion height. Conclusion: The safe position for OMSI placement at the IZC was 13.69-16 mm from the maxillary occlusal plane with an insertion angle between 55° and 75°. These parameters provide the optimum placement of OMSIs along the distobuccal root of the permanent maxillary first molar.

Background Oral malignancy that presents at a locally advanced stage needs complex surgical resections in which the maxillary cavity is usually left open. The constant maxillary secretions lead to problems like poor healing, fistula formation, and flap necrosis, causing longer hospital stays, delayed adjuvant therapy, and additional surgeries. Several methods have been tried to ameliorate this, each faced with its own difficulties. This study describes the use of chimeric free anterolateral thigh (ALT) with vastus lateralis (VL) muscle to tackle this problem.

Background: Digitalization in the form of increased Internet use through screen media has also shown its ramification like cyberbullying. They are aggressive acts with the intention or motivation to harm another person through technology. The aim is to study the prevalence of cyberbullying and its association with mental illness in the adolescent age group (15–19 years). Methods: This community-based cross-sectional study was rolled out among adolescents aged 15–19 years. A total of 387 were given a semistructured interviewer-administered questionnaire consisting of general details, cyberbullying victimization, and offending questions, PHQ-9 and GAD-7. Results: The mean (SD) age was 16.8 (1.3) years. More than half (53.2%) were males, and nearly three-fourths (74.4%) were school-going. Around 28.2% reported being cyberbullied at least once in their lifetime. About 7.0% of adolescents were cyberbullied more than once, and 0.8% more than five times in the past 30 days. The most common ways were posting a mean or hurtful picture (31.9%) and the concerned person’s comments (24.2%) online. Multivariable logistic regression analysis found that adolescents attending colleges (AOR 1.9, 95% CI 1.1 to 3.4), using tobacco (AOR 2.5, 95% CI 1.4 to 4.5), and depressed (of any severity, AOR 2.0, 95% CI 1.1 to 4.3) were at significantly increased risk of being cyberbullied (P < 0.05). Conclusion: The prevalence of cyberbullying among adolescents aged 15–19 is notable, with significant associations found between cyberbullying and attending college, tobacco use, and depression. Understanding the correlates of cyberbullying can inform targeted interventions to support mental health and well-being among adolescents.

Background: Urolithiasis is a common urinary tract disease in buffaloes, almost exclusively affects young males, and has significant economic and production impacts. We have investigated hemato-biochemical and urinary changes in an attempt to deduce their correlation with struvite urolithiasis in buffaloes. Methods: Ten male buffalo calves with obstructive urolithiasis were used. Blood samples were used for hematology and elemental analysis. Urine samples were used for physico-chemical examination, microscopy, and elemental analysis. Uroliths were subjected to chemical functional group determination using the FTIR spectroscopy. Results: The mean neutrophil, leukocyte, and neutrophil-to-lymphocyte ratio was significantly (p < 0.05) higher in urolithic buffaloes than in healthy controls. The mean blood calcium and magnesium concentrations were significantly (p < 0.05) lower and higher in urolithic buffaloes than in healthy controls, respectively. Mean blood phosphorus concentration and calcium-phosphorus ratio were found to be non-significantly (p > 0.05) higher and lower in urolithic buffaloes than in healthy controls, respectively. The urine pH was highly alkaline. Multiple prismatic lid-shaped crystals, along with erythrocytes, leukocytes, and epithelial cells, were found in urine. The mean urinary magnesium and phosphorus concentrations were non-significantly (p < 0.05) higher in urolithic buffaloes than in healthy controls. A positive correlation of magnesium (r = 0.864, p = 0.001) and phosphorus (r = 0.849, p = 0.002) concentrations between the blood and urine was observed in urolithic buffaloes. The FTIR spectra of uroliths were similar to those of magnesium ammonium phosphate hexahydrate, MgNH4PO4·6H2O or struvite. Conclusion: The findings suggest that high plasma magnesium and phosphorus concentrations have a positive correlation with struvite urolithiasis in buffaloes.

Abstract Background An aneurysmal bone cyst is a locally destructive benign lesion affecting mostly the long bones. Aneurysmal bone cyst of the skull bones is a very rare phenomenon and the involvement of the sphenoid bone of the skull with extension into the orbit is even rarer. We present a case of 15-year-old adolescent with fibrous dysplasia of the sphenoid wing with secondary aneurysmal bone cyst. Case presentation A 15-year-old male presented to us with chief complaints of headache with swelling in the left temporal region of the face and proptosis of the left eye associated with decreased vision for the past 2 months. NCCT showed a large heterogeneous mass in the left temporal region extending into left orbit. Gadolinium-enhanced MRI showed a well-defined multiloculated osteo-expansile lesion in the left middle cranial fossa extending into the anterior cranial fossa consistent with the fibrous dysplasia of the sphenoid bone with associated aneurysmal bone cyst. Digital subtraction angiography brain to look for any feeders to the lesion was done followed by microsurgical gross total excision of the tumor. The histopathology report confirmed it to be fibrous dysplasia secondary to aneurysmal bone cyst. Conclusion Aneurysmal bone cyst is a rare entity, commonly affecting the long bones of the body. The involvement of sphenoid wing of skull is very rare occurrence. It can be primary or secondary to fibrous dysplasia, chondroblastoma, giant cell tumor, fibromyomas, etc. Fibrous dysplasia with secondary aneurysmal bone cyst should be kept in mind as one of the differential diagnoses while dealing with osteolytic bone lesions of skull.

Abdomen provides a donor site abundant in skin and subcutaneous tissue, amenable to primary closure; sizeable, robust, and consistent perforators and a long, sizeable pedicle for comfortable microvascular anastomosis. Its offers all the donor variables needed for HN reconstruction in abundance.

The present study deals with the erosive wear behaviour of a zinc-aluminum (ZA) alloy and composite in the slurry medium. The effects of reinforcement of zirconium diboride (ZrB2) particles in ZA alloy, as well as the impingement angle and duration of erosion wear responses have been studied. The slurry composition was prepared with 1.5 L of water and 500 g silica of a size range of 350–450 μm. The erosion tests are performed at a speed of 600 rpm for varying durations (20–80 h) and impingement angles (30°–90°). The erosive wear responses of the samples have been analyzed in terms of distinct features of their micro constituents like ZrB2 and the material removal mechanism in a prescribed set of conditions. A significant decrease in composite erosion compared to ZA alloy has been observed. With increased duration, both alloy and composite show increased erosive wear. Obtained results revealed that the composite shows 60–80 % less erosive wear than ZA alloy on operating conditions. The optimum results in wear have been observed at 45° for alloy and 60° for composite. Investigating topographical aspects using scanning electron microscopy and atomic force microscopy revealed that ZrB2 reinforcements resulted in smoother topography and reduced erosive wear.

In the present study, genetic screening of Sahiwal and Holstein Friesian (HF) cattle and its crosses was conducted using the PCR-RFLP technique to detect the presence of CVM and DUMPS disorders. Genomic DNA was extracted from 50 Sahiwal and 100 HF animals and its crosses using commercially available kits. Gene-specific primers were utilized for in vitro amplification of SLC35A3 and UMPS genes by PCR, followed by RFLP analysis using PstI and AvaI restriction endonucleases for CVM and DUMPS, respectively. Subsequently, the PCR products were purified and sequenced to confirm any mutations in the DNA target sequences. Notably, no affected or carrier animals for CVM and DUMPS disorders were identified among the screened animals. Thus, the gene and genotype frequency of CVM and DUMPS carriers was zero, indicating a 100% frequency of normal animals. The study underscores the importance of continued screening for these genetic disorders, involving a larger sample size across the state, and advocates for mandatory screening before utilizing animals for breeding purposes, in adherence to minimum standard protocols.

Use of the green approach for the synthesis of nanoparticles has gained significant interest in the field of nanotechnology. The applicability of greener nanomaterials in environmental remediation has unveiled their tremendous properties and potentiality to eradicate the pollutants from nature in ecofriendly manner. In the present paper, we proposed synthesis of TiO2-Al2O3-ZnFe2O4 nanocomposites using flower extract of Hibiscus rosa sinesis via hydrothermal approach. The synthesized product was characterized by several optical and morphological techniques i.e. Field emission scanning electron microscope, X ray diffraction, energy dispersive spectroscopy, Fourier transform infrared spectroscopy and Brunauer Emmett Teller. To conclude, Field emission scanning electron microscope reveals the nanostructures are of 40-130 nm size. X ray diffraction reveals the presence of rutile TiO2 and hexagonal Al2O3 along with ZnFe2O4 crystallites. Barrett-Joyner-Halenda model reveals that the pore volume and pore diameter were found to be 38.206 m2/g, 0.048 cc/g and 3.640 nm, respectively. TiO2-Al2O3-ZnFe2O4 have shown photocatalytic degradation of methylene blue (96.54 ± 1.24%.), industrial sample (88.52 ± 0.64), and heavy metal hexavalent chromium (94.7 ± 3.20%) in the presence of sunlight. Besides, the synthesized product exhibited good antioxidant properties (84 ± 2.1%) against 2,2-diphenyl-1-picrylhydrazyl.
