Abstract:

In the central Himalaya, plants are subjected to a prolonged dry period, thus developing moisture stress. Variations in water relations and their response to drought in a Himalayan tree species, Schima wallichii at 1400 m elevation were studied at Phulchowki Hill, Kathmandu, Nepal. To understand the adaptational strategy of this species through which it withstands water stress, different parameters such as soil water potential at 15 (Y15) and 30 (Y30) cm depths, tree water potential at predawn (Ypd) and midday (Ymd), leaf conductance during morning (gw AM) and afternoon (gw PM) and correlation

Abstract:

Background: Asthma is one of the most prevalent chronic respiratory diseases among children, markedly impairing patient’s health and imposing an increasing burden on the healthcare system. Several traditional Chinese medicines have demonstrated efficacy in alleviating asthma symptoms through studies conducted on animal models. Recent studies have shown that the Yunpi Xiefei Huatan Tang decoction (YPD) exhibits significant therapeutic outcomes in treating phlegm-obstructed pulmonary asthma. However, the precise regulatory effects of YPD on the progression of asthma require additional investigat

Weak growth of seven yeast isolates (YP3, YP4, YP7, YP8, YP11, YP12 and YP15) was occurred at 45°C. Yeast isolates could grow at pH range (pH3 to pH6) and their optimum growth was occurred at pH3 and pH4. Moreover, isolated yeast strains were tolerant to ethanol concentration of 5%.

Abstract:

AbstractRecent investigations suggested pigeon associated Rotavirus Typ A genotype G18P[17] (RVA) as a causative agent of the classical ‘young pigeon disease’ (YPD). YPD was first described in the late 1980 s as an acute, mainly seasonally recurring disorder of mostly juvenile domestic pigeons (Columba livia) with clinical signs such as anorexia, dairrhea, vomiting, congested crops, weight loss and occasionally mortality. Various studies in the past indicated a multifactorial nature of YPD. Several pathogens, such as pigeon circovirus 1, avian adenoviruses and Escherichia coli were also sugges

Abstract:

IMMH-010 is an ester prodrug of YPD-29B, a potent programmed cell death ligand 1 (PD-L1) inhibitor. The metabolism of IMMH-010 was investigated and compared in various species. Four metabolites of IMMH-010 were identified, and the major metabolite was the parent compound, YPD-29B, which was mainly catalyzed by carboxylesterase 1 (CES1). We observed IMMH-010 metabolism in the plasma of various species. IMMH-010 was rapidly metabolized to YPD-29B in rat and mouse plasma, whereas it remained stable in human and monkey plasma.

The results showed that cytosolic extracts exhibited higher lipase activity when cells were grown in YPD. Under nitrogen starvation, lipase activity was not detected after 24 h of culture, resulting in lipid accumulation in LDs. This sug

With conventional methods, only a continuously stirred tank reactor configuration gave high aeration rates for cultures in yeast extract peptone dextrose (YPD) medium.

Abstract:

Saccharomyces cerevisiae is exceptional microorganisms used in biotechnological processes, mainly in the ethanol production chain. Studies of the cellular responses of industrial yeasts under ethanolic and thermal stress in an association are still incipient. This study aimed to evaluate the action of thermal and ethanolic stress in industrial strains of Saccharomyces cerevisiae under different temperatures and concentrations of ethanol, to understand whether these factors influence ethanol production. For cytotoxicity and genotoxicity tests, yeasts were grown in 2% YPD medium incubated for 10

Abstract:

Transcription factors are proteins encoded in an organism's genome that regulate gene expression and control various biological activities. In fungi, many of these transcription factors are proteins with unidentified functions until now, particularly those that regulate genes associated with Candida albicans cell wall biosynthesis. This process is vital for fungal bioactivity and sensitivity to some antifungal agents. This study investigates Mig1 and Orf19.173 transcription factors in response to caspofungin in different environmental conditions as an initial step toward understanding their ro

A constitutive expression system with the glyceraldehyde-3-phosphate dehydrogenase promoter (pGAP) with homology arms for the glycerol kinase 1 (GUT1) was constructed for the targeted integration of the expression plasmid in a KU70 def

Single and multiple aldΔ mutants were generated in the wine-yeast-derived V5 and laboratory CEN.PK strains and analysed under standard (YPD 5 % glucose) and wine (MS 20 % glucose) fermentation conditions.

The effect of water stress during the harvest period on carbohydrate reserves at the end of the growing season was studied for mature, field-grown almond trees.

Therefore, it is crucial to analyze the underlying causes of these variations at the molecular level.

Abstract:

Abstract Four genes encoding the major egg yolk polypeptides of the Mediterranean fruit fly Ceratitis capitata, vitellogenins 1 and 2 (VG1 and VG2), were cloned, characterized and partially sequenced. The genes are located on the same region of chromosome 5 and are organized in pairs, each encoding the two polypeptides on opposite DNA strands. Restriction and nucleotide sequence analysis indicate that the gene pairs have arisen from an ancestral pair by a relatively recent duplication event. The transcribed part is very similar to that of the Drosophila melanogaster yolk protein genes Yp1, Yp2
