Awareness of breast cancer has been increasing due to early detection, but the advanced disease has limited treatment options. There has been growing evidence on the role of miRNAs involved in regulating the resistance in several cancers. We performed a comprehensive systematic review and meta-analysis on the role of miRNAs in influencing the chemoresistance and sensitivity of breast cancer. A bibliographic search was performed in PubMed and Science Direct based on the search strategy, and studies published until December 2018 were retrieved. The eligible studies were included based on the selection criteria, and a detailed systematic review and meta-analysis were performed based on PRISMA guidelines. A random-effects model was utilised to evaluate the combined effect size of the obtained hazard ratio and 95% confidence intervals from the eligible studies. Publication bias was assessed with Cochran’s Q test, I2 statistic, Orwin and Classic fail-safe N test, Begg and Mazumdar rank correlation test, Duval and Tweedie trim and fill calculation and the Egger’s bias indicator. A total of 4584 potential studies were screened. Of these, 85 articles were eligible for our systematic review and meta-analysis. In the 85 studies, 188 different miRNAs were studied, of which 96 were upregulated, 87 were downregulated and 5 were not involved in regulation. Overall, 24 drugs were used for treatment, with doxorubicin being prominently reported in 15 studies followed by Paclitaxel in 11 studies, and 5 drugs were used in combinations. We found only two significant HR values from the studies (miR-125b and miR-4443) and our meta-analysis results yielded a combined HR value of 0.748 with a 95% confidence interval of 0.508−1.100; p-value of 0.140. In conclusion, our results suggest there are different miRNAs involved in the regulation of chemoresistance through diverse drug genetic targets. These biomarkers play a crucial role in guiding the effective diagnostic and prognostic efficiency of breast cancer. The screening of miRNAs as a theragnostic biomarker must be brought into regular practice for all diseases. We anticipate that our study serves as a reference in framing future studies and clinical trials for utilising miRNAs and their respective drug targets.

"nBackground: Job satisfaction remains as an important concern for both employer and employee. The leaving of work­place and migration to city centers is one of the main results of Job dissatisfaction among the primary health care (PHC) provid­ers in rural setting of Iran, Behvarzes. Determining the predictor's factors of the PHC providers' job dissatisfac­tion and provid­ing appropriate strategies to address these factors can most likely improve their performance and dimin­ish the prob­lem."nMethods: Data were collected from 290 of the PHC providers worked full-time in Kurdistan rural health-house by a sur­vey for identifying the individual, environmental, and work factors that influence job satisfaction."nResults: Only 17% of the participants' overall job satisfaction was high. Furthermore, the developed model presented sta­tistically significant differences between job satisfaction and village population size, satellite villages covered, and dis­tance between health-house and city center."nConclusion: It is expected that the finding of the study can help Iran health system policymakers and managers for plan­ning and implementing effective policies in order to meet the PHC providers' needs and so improve quality of pri­mary health care in the rural areas.

Abstract The novel coronavirus SARS-CoV-2 resulted in a significant worldwide health emergency known as the COVID-19 pandemic. This crisis has been marked by the widespread of various variants, with certain ones causing notable apprehension. In this study, we harnessed computational techniques to scrutinize these Variants of Concern (VOCs), including various Omicron subvariants. Our approach involved the use of protein structure prediction algorithms and molecular docking techniques, we have investigated the effects of mutations within the Receptor Binding Domain (RBD) of SARS-CoV-2 and how these mutations influence its interactions with the human angiotensin-converting enzyme 2 (hACE-2) receptor. Further we have predicted the structural alterations in the RBD of naturally occurring SARS-CoV-2 variants using the tr-Rosetta algorithm. Subsequent docking and binding analysis employing HADDOCK and PRODIGY illuminated crucial interactions occurring at the Receptor-Binding Motif (RBM). Our findings revealed a hierarchy of increased binding affinity between the human ACE2 receptor and the various RBDs, in the order of wild type (Wuhan-strain)

Paleomagnetic records from the sediments provide the foundation for studying variations in the geomagnetic field across the geological time sacle. Here, we report a new paleomagnetic data from Quaternary sediments of Ramganga Paleolake, NW Himalaya, India, to provide more insight into the global geomagnetic excursions and paleoenvironmental implications. Paleomagnetic and rock magnetic analyses were performed on a 5 m thick vertical profile of unconsolidated sediments from the Ramganga paleolake (29°46′867″N; 79°14′043″E), located in the Lesser Himalaya at a height of 798 m. One hundred fifty oriented samples from 50 sites (10 cm intervals) were obtained from the vertical section. Extrapolating the optically stimulated luminescence (OSL) dates from literature indicates that the entire section was probably deposited between 38 and 0.8 ka. The rock magnetic data shows that the remanence is carried by a low coercivity mineral and a significant amount of a soft magnetic mineral, most likely magnetite. Virtual Geomagnetic Pole (VGP) latitudes were calculated. Plot of the VGP latitudes against the sample locations from the litho-column allows us for the construction of Magnetic Polarity Stratigraphy (MPS) column. The MPS of the Ramganga paleolake has detected three geomagnetic excursions that are correlated with the global events: the Mono Lake Event (∼28.4-25.8 ka), the Gulf of Mexico Event (∼12.5–17 ka), and the Bagwalipokar Excursion Events (15.5-14.7 ka and 8-2.85 ka) respectively. The lower and middle portion of the paleolake represents the low and high energy depositional environment during the sediment deposition due to wet and arid climatic conditions.

This study investigates the mechanical, fatigue, and creep properties of commercial plywood (6 mm) alternative polyester composite prepared using waste plastic core, hemp fiber, and shrimp shell powder. The primary aim of this research was to develop an exact replacement for plywood building material and study the effect of fiber stacking order as well as the volume fraction of shrimp shell biopolymer on load-bearing and time-dependent properties. Composites' distinct quasi-isotropic stacking orders with varying hemp fiber angles and shrimp filler contents of 0%, 1.0%, and 3.0% were prepared via compression molding and tested based on ASTM standards. Results revealed that the "D" stacking order {(−45/45) + (−30/60) + WPC + (−60/30) + (−45/45)} composite consistently outperformed others, exhibiting superior mechanical strength. Specifically, the D2 composite exhibited elevated strength, including a tensile strength of 168 MPa, flexural strength of 199 MPa, compression strength of 181 MPa, impact energy of 6.23 J, interlaminar shear strength of 25.9 MPa, and v-notch rail shear of 19.7 MPa. The addition of shrimp filler, rich in hydroxyl groups, enhanced intermolecular interactions, contributing to a resilient network and improved fatigue resistance. Moreover, the creep resistance was notably influenced by the quasi-isotropic arrangement, with the "D" designation showcasing optimal performance. Microscopic analysis revealed the critical role of shrimp shell content in promoting cohesion and interlocking fiber structures. The findings underscore the intricate synergy between stacking angles; filler composition and content in achieving robust and eco-friendly polyester composite building material to replace the termite, weather, and water affect commercial plywood.
