Understanding the pathophysiology of coronavirus disease 2019 (COVID-19) infection remains a significant challenge our times. The gingival crevicular fluid being representative systemic status and having proven track record detecting viruses biomarkers forms logical basis for evaluating presence severe acute respiratory syndrome 2 (SARS-CoV-2). study aimed to assess (GCF) evidence SARS-CoV-2 in 33 patients who were deemed be COVID-19 positive upon nasopharyngeal sampling. An attempt was also...

Embryonic stem (ES)‐like cells were derived from mid‐blastula stage embryos of a freshwater fish, catla Catla , under feeder‐free condition and designated as CCES cells. The conditioned media was optimized with 10% foetal bovine serum (FBS), fish embryo extract (FEE) having 100 µg ml −1 protein concentration, 15 ng basic fibroblast growth factor (bFGF) containing Leibovitz‐15, DMEM 4·5 g l glucose Ham's F12 (LDF) in 2:1:1 ratio using primary culture Cells attached to gelatin‐coated plates...
Recently, there has been a noticeable increase in fluoride contamination drinking water, leading to evident harmful effects various locations. Tackling the challenge of reducing levels potable water become significant concern for supply agencies. In our current study, we focused on creating and characterizing different adsorbents, namely sugarcane bagasse, coconut husk, rice their ability effectively remove fluoride. These adsorbents are not only cost-effective readily available but also...

This study aimed at developing a suitable cryopreservation protocol for embryonic stem (ES)-like cells of tiny freshwater fish Leopard danio (Brachydanio frankei). Embryonic derived from blastomeres the early blastulae stage embryo were cultured in vitro medium containing Leibowitz-15 supplemented with 10% foetal bovine serum, leopard extract, sodium bicarbonate, selenite, basic fibroblast growth factor, epidermal factor and leukaemia inhibitory factor. The ES-like showed properties similar...
The milt quality parameters such as percentage of spermatozoa motility, duration sperm concentration, and seminal plasma composition Cirrhinus Mrigala (C.mrigala) varied throughout the breeding season i.e. from April to September.The motility (second) was low in beginning ie.April (42 ± 4.32) recorded a peak 97.5 4.12 during July again started declining reached 39 4.76 at end season.The mean pH values ranged 8.05 0.19 8.6 0.12 with maximum July.The osmolality highest 291.5 mOsm kg -1...
Cryopreservation of gametes and germ cells is an essential tool for germplasm conservation improvement productivity in aquaculture. Here, transplantation worthiness isolated cryopreserved (GCs) Indian major carp, rohu Labeo rohita has been tested by their viability colonization ability the allogenic host ( Catla catla ). GCs were using dimethyl sulphoxide (DMSO), ethylene glycol (EG) glycerol. Rohu successfully with significantly higher slow cooling rate -1C/min a medium containing 1.4 M...
Newer coexisting conditions should be identified in order to modify newer risk factors. Aim was identify patients with non-classical or less common infected of COVID 19.
Background: Trauma in Himachal Pradesh is an increasingly significant problem, particularly light of rapid development and increasing motorization. In the state due to predominantly hilly terrain people are more vulnerable accidents, resulting various injuries. Moreover, increase industrialization, ongoing construction hydel projects subsequent accidents have also affected incidence trauma. Social environmental changes alterations epidemiology The present study was done pattern, cause, mode...

Inhalabte dust, total dust and respirable by cyclone horizontal elutriator were measured in a side-by-side area (static) sampling programme at eight selected ferrous non-ferrous foundries. Forty sets of samples collected the relationships between four different measurements examined. In foundry environments surveyed, correlated highly with inhalabte concentration. The MRE (Casella 113A) operating 2.5 l. min −1 flow rate, matching BMRC criterion, generally more weight per m 3 air than 10 mm...
Effect of priming on the maturation and spawning were tested in two fish species using gonadotropin-releasing hormone (GnRH), carp pituitary homogenate (CPH) clomiphene citrate (clomid). The injected with a dose GnRH, CPH clomid, calibrated to contain 0.3ml/kg, 7 mg/kg 70mg/kg respectively three split doses (two one final dose). Two enhanced as evident from assay, histology gamete analysis. Among inducing agents, GnRH showed 94% higher GSI (5.31♂;18.5♀) than clomid rohu. Subsequently,...
The viability of matured oocytes stored in vitro were assessed using carp ovarian fluid (OF) and artificial (ACOF) under different temperature regimes (4, 24, 26, 28 30°C) for storage durations (0, 60, 120, 150 180 min). Significantly higher fertilization (74%) was achieved when the ACOF 65% OF after min at 28°C. Similarly hatching rates larvae significantly OF, that is, 64% 47%, respectively, storage. kept containers with having moisture level showed a rate than 59% level. This study...
Abstract Background Carp fish, rohu ( Labeo rohita Ham.) is important freshwater aquaculture species of South-East Asia having seasonal reproductive rhythm. There no holistic study at transcriptome level revealing key candidate genes involved in such circannual rhythm regulated by biological clock (BCGs). Seasonality manifestation has two contrasting phases reproduction, i.e., post-spawning resting and initiation gonadal activity appropriate for the associated genes. It can be deciphered RNA...
The present work assessed the seasonal changes in germ cells (GC) and maturation of rohu, Labeo rohita tilapia, Oreochromis niloticus. Here, we showed two species representing diverse types spawning behavior, having distinct GC proliferation patterns. During July, a single peak season for rohu was recorded with highest GSI (female: 19.5±1.29 male 4.2±0.24), which is monsoon time Eastern India. However, seasons were marked tilapia during pre-monsoon (April) post-monsoon (October) period...
