Abstract A total of seventy irrigation water samples were collected from Leh, Ladakh, India, to determine their hydrochemistry profile and quality for purposes. Water indices such as hardness (TH), residual sodium carbonate (RSC), potential salinity (PS), permeability index (PI), Kelly's ratio (KR), absorption (SAR), corrosivity (CR), chloroalkaline (CAI) measured. The Piper diagram, Durov's United States Salinity Laboratory (USSL) diagram drawn the types, ion exchange processes,...

For nearly a decade, silver nanoparticles (AgNPs) have been the most prevalent commercial nanomaterials products widely used in different biomedical applications due to their broad-spectrum antimicrobial activity. However, poor long-term stability environments, namely, pH, ionic strength, and temperature, cytotoxicity toward mammalian cells has restricted more extensive applications. Hence, there is urgent need develop highly biocompatible, non-toxic, stable for wide-ranging environments In...

Monitoring water quality of surface resources is the key concern in determining potable high-altitude region. Therefore, there a need to evaluate different parameters affecting river and identify most important variables factors significantly quality. In present study, multivariate statistical methods including cluster analysis principal component analysis/factor were applied analyze Indus River Trans-Himalayan region India. For this total 25 no. physicochemical analyzed samples taken from...

The high-altitude region represents the extreme climatic condition that may have an adverse effect on body weight and alteration in stress markers of livestock animals. Thus, aim our study was to evaluate different morphological traits biochemical breeds goat at Leh-Ladakh, India. In this study, 27 adult female goats three like Changthangi—a native breed high altitude, Sirohi—a low lander from plain area, Crossbred—Changthangi × Sirohi. After 330 days rearing, a comparative assessment seven...

Many factors have been found responsible for the groundwater quality like interaction of different water sources, types soils, other several natural factors, and anthropogenic factors. Therefore, objectives present work were to identify affecting ground based on multivariate analysis. This study also aimed determine usefulness statistical techniques improve our understanding properties their interactions. The original matrix consisted 25 physico-chemical parameters analyzed in 70 number...

<p>Goat meat (chevon) comprises an important source of protein to provide essential amino acids in addition other and plant sources proteins. Therefore, demands for chevon are huge from civil defence sector this region. However, there is limited availability fresh tender Ladakh region round the year. Hence, was a need augmenting local goat by developing animal technology fast growing region-specific crossbred purpose that can efficiently perform under adverse climatic conditions...

As the altitude increases, partial pressure of oxygen decreases, leading to hypoxic conditions and ultimately disturbing body homeostasis affecting neuroendocrine function in cattle. These physiological changes cause low conception rate, early embryonic death, fertility, etc., cattle other livestock species. So far, cattle's reproductive health associated with high-altitude has rarely been studied concerning physiology, endocrinology, physio-biochemical perspective. Hence, this review...

This study shows an effective but simple method of conserving characterised populations through seed germination modification and treatment with plant growth regulators. It is tolerant to cold temperature, as would be expected a Himalayan plant, not dry conditions. Podophyllum hexandrum dormancy has been considered major constraint most the earlier reports recommended breaking pre-treatments such chilling, gibberellic acid (GA3). However, in this study, we showed that pre-treatment seeds...

The present study was aimed to investigate the effect of physico-chemical parameters and soil macro-nutrients know nutrient uptake status during sowing time (ST) after harvesting (AH) crops Leh-Ladakh. In this context, total 55 no. samples were collected from eleven villages. Thereafter, texture, pH, electrical conductivity (EC), dissolved solids (TDS), organic carbon (OC), nitrogen (N), phosphorus (P), potassium (K) analyzed as per standard methods. results exhibited variation in different...

The present study was carried out for 7 days on four adult low-lander single-humped camels to know the effectof endurance load exercise physiological, biochemical, hormonal, and inflammatory cytokines at high altitude.A significant 1.5 3 fold increase observed in physiological responses, viz. respiration heart rate onthe 1st 7th day after exercise. Further, serum triglycerides levels were significantly increased exercise, whereas other biochemical parameters unaffected. However, hormones...

This study was conducted to evaluate the protective effects of melatonin against fluoride-induced oxidative stress-mediated haematological and biochemical changes in rat at high altitude. Adult male Wistar rats (6) were given basal diet drinking water ad lib. for first 7-days which considered as control period. Thereafter, they exposed NaF (@ 50 ppm) per-oral through next 14 days followed by treatment 15 mg/kg BW, p.o.) days. The result showed induction stress during alone, caused...
