Simulated microgravity environment inhibits matrix mineralization during the osteoblast to osteocyte differentiation.

This study investigates the effects of microgravity on the differentiation and mineralization of IDG-SW3 osteocyte-like cells to understand the response of bone cells to microgravity and develop strategies to mitigate bone loss in astronauts. IDG-SW3 cells were cultured in collagen-coated dishes and subjected to a 3D clinostat to simulate microgravity 14 days after initiating differentiation. The static group remained under normal gravity.

Heat Stress-Tolerant Quantitative Trait Loci Identified Using Backcrossed Recombinant Inbred Lines Derived from Intra-Specifically Diverse Accessions.

In the face of climate change, bringing more useful alleles and genes from wild relatives of wheat is crucial to develop climate-resilient varieties. We used two populations of backcrossed recombinant inbred lines (BIL1 and BIL2), developed by crossing and backcrossing two intra-specifically diverse accessions from lineage 1 and lineage 2, respectively, with the common wheat cultivar 'Norin 61'. This study aimed to identify quantitative trait loci (QTLs) associated with heat stress (HS) tolerance.

An abattoir study of the prevalence of foot lesions and claw measurements in water buffalo in Egypt.

Background: Lameness has been associated with compromised animal welfare and reduced productivity in dairy cattle herds worldwide. However, little is known about the prevalence of claw lesions in the dairy buffalo population in Egypt. Furthermore, the optimum measurements for claw trimming in buffalo are unknown.

A cross-sectional study of the prevalence of lameness and digital dermatitis in dairy cattle herds in Egypt.

Background: Lameness is a significant problem for the dairy industry worldwide. No previous studies have evaluated the prevalence of lameness or digital dermatitis (DD) in dairy cattle herds in Egypt. A total of 16,098 dairy cows from 55 dairy herds in 11 Egyptian governorates underwent visual locomotion scoring using a 4-point scoring system.

Local administration of HMGB-1 promotes bone regeneration on the critical-sized mandibular defects in rabbits.

Reconstruction of a critical-sized osseous defect is challenging in maxillofacial surgery. Despite novel treatments and advances in supportive therapies, severe complications including infection, nonunion, and malunion can still occur. Here, we aimed to assess the use of a beta-tricalcium phosphate (β-TCP) scaffold loaded with high mobility group box-1 protein (HMGB-1) as a novel critical-sized bone defect treatment in rabbits.

Officially Confirmed COVID-19 and Unreported COVID-19-Like Illness Death Counts: An Assessment of Reporting Discrepancy in Bangladesh.

Reporting discrepancies between officially confirmed COVID-19 death counts and unreported COVID-19-like illness (CLI) death counts have been evident across the world, including Bangladesh. Publicly available data were used to explore the differences between confirmed COVID-19 death counts and deaths with possible COVID-19 symptoms between March 2, 2020 and August 22, 2020. Unreported CLI death counts totaled more than half of the confirmed COVID-19 death counts during the study period.

Double-locus sequence typing using porA and peb1A for epidemiological studies of Campylobacter jejuni.

Campylobacter jejuni is the leading cause of foodborne bacterial gastroenteritis worldwide. Bacterial typing schemes play an important role in epidemiological investigations to trace the source and route of transmission of the infectious agent by identifying outbreak and differentiating among sporadic infections. In this study, a double-locus sequence typing (DLST) scheme for C.

Evaluation of current molecular approaches for genotyping of Campylobacter jejuni strains.

Campylobacter jejuni has been recognized as the most common bacterial cause of gastroenteritis worldwide, in both developed and developing countries, since the late 1970s. A number of genotyping schemes have been developed to identify the sources and route of transmission of these foodborne pathogens so that proper control measures can be developed. In this review, we provide current genotypic schemes developed for Campylobacter spp.

Monitoring antimicrobial susceptibility of Neisseria gonorrhoeae isolated from Bangladesh during 1997-2006: emergence and pattern of drug-resistant isolates.

Gonorrhoea is one of the most common sexually transmitted infections (STIs) in developing countries, and the emergence of resistance to antimicrobial agents in Neisseria gonorrhoeae is a major obstacle in the control of gonorrhoea. Periodical monitoring of antimicrobial susceptibility of N. gonorrhoeae is essential for the early detection of emergence of drug resistance.
