Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder that affects large proportion of women. Due to its heterogeneity, the best diagnostic strategy has been matter contention. Since 1990 scientific societies in field human reproduction have tried define pivotal criteria for diagnosis PCOS. The consensus Rotterdam included presence hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology (PCOM), now updated evidence based 2018 2023 International Guideline endorsed by...
Microbial corrosion of concrete in sewers is known to be caused by hydrogen sulfide, although the role wastewater regulating processes poorly understood. Flooding and splashing periodically inoculates surface sewer pipes. No study has systematically investigated impacts inoculation on sewers. This development microbial community, sulfide uptake activity, change properties for coupons subjected periodic inoculation. The were exposed different levels under well-controlled conditions...
Iron(III) (oxyhydr)oxide minerals with varying particle sizes commonly coexist in natural environments and are susceptible to both chemical microbial reduction, affecting the fate mobility of trace elements, nutrients, pollutants. The size-dependent reduction behavior iron (oxyhydr)oxides single mixed mineral systems remains poorly understood. In this study, we used mediated electrochemical approaches investigate kinetics extents goethite hematite. We found that small particles were...
In Hong Kong, cattle were traditionally raised by farmers as draft animals to plough rice fields. Due urbanization in the 20th century, they gradually abandoned and became wild straying suburban Kong. Recently, these observed have become omnivorous eating leftover barbeque food waste country parks. Microbiome analysis was performed on fecal samples of using deep sequencing resulting microbiome compared with that traditional herbivorous Southern China. A more diverse gut cattle, suggesting...
Three bacterial strains, HKU70T, HKU71T and HKU72T, were isolated from the conjunctival swab, blood sputum samples of three patients with conjunctivitis, bacteraemia respiratory infection, respectively, in Hong Kong. The strains aerobic, Gram-stain positive, catalase-positive, non-sporulating non-motile bacilli exhibited unique biochemical profiles distinguishable currently recognized Tsukamurella species. 16S rRNA, secA, rpoB groEL gene sequence analyses revealed that shared 99.6-99.9,...
The morphology of pyrite has been used to infer ancient redox states and biogenicity.However, the influence trace metals on is poorly understood.Through batch synthesis experiments, we demonstrate that bioessential (Co, Cu, Mo, Ni, Zn) accelerate formation.The first precipitate, FeS am , transformed an intermediate greigite phase with increasing time temperature.Trace either facilitated polysulphide formation or precipitated as nanoparticles can serve nuclei for growth, depending initial...
Three bacterial strains, HKU63T, HKU64 and HKU65T, were isolated from the conjunctival swabs of three patients with conjunctivitis in Hong Kong. The strains aerobic, Gram-stain-positive, catalase-positive, non-sporulating non-motile bacilli exhibited unique biochemical profiles distinguishable closely related Tsukamurella species. 16S rRNA gene sequence analysis revealed that shared identical sequences each other, being most to tyrosinosolvens pulmonis, sharing 99.9 % identity. Sequence...
Abstract Biogenic magnetite is a potential biosignature for microbial iron cycling in hydrothermal sulfide systems, critical environments unraveling the emergence and early evolution of life. However, preservation biogenic under conditions poorly understood. Here, we show that sulfidation abiogenic (sulfide/iron = 4, 80 °C) yields pyrite with various distinct morphologies, including framboid-like spheroids. We demonstrate variability morphologies resulted from modulation pyritization rates...
In this study, we reported the prevalence and mechanism associated with extended-spectrum beta-lactamase (ESBL)-positive phenotype in Laribacter hongkongensis isolated from patients fish. Using inhibition zone enhancement test, 20 (95.2%) of 21 patient strains 8 (57.1%) 14 fish were tested ESBL-positive. However, ESBL genes, including SHV, TEM, CTX-M, GES, PER, not detected all these 28 L. isolates. No gene could be either complete genome HLHK9 or draft PW3643. PCR DNA sequencing revealed...
Glanders is a highly contagious and potentially serious disease caused by Burkholderia mallei , Tier 1 select agent. In this study, we raised monoclonal antibody (mAb) against the lipopolysaccharide (LPS) of B . developed competitive enzyme-linked immunosorbent assay (cELISA) for infection. Using titrated optimal conditions mallei- LPS (2 ng) microtiter plate coating, sample serum dilution at 1:20 3.5 ng/μL anti-LPS mAb B5, cutoff value cELISA was determined using samples from 136...
Abstract Patients admitted for treatment of in vitro fertilization (IVF) were subjected to a semen investigation about 1–2 weeks prior actual IVF and again during IVF. In addition routine analyses, the recovery efficiency motile spermatozoa by swim‐up technique Percoll gradient separation, level lactate dehydrogenase viability insemination medium also studied. There is significant correlation between result pre‐IVF analyses that observed suggesting profile sperm function useful screen...
