Climate change brings extreme events like drought, landslide, flood and anticipated more constraint to profitable livestock production causing huge economical loss in the livestock sector of the country. Deaths of livestock and damage to farms and farm infrastructure is causing a huge loss, small livestock holders are highly venerable to such climatic hazards. So to cope with these uncertain climatic hazards livestock insurance is the one of the best strategies. This study reveals that different climatic hazards is been experienced by the livestock holders of Kaski, Dolakha and Jhapa district of Nepal, 62% of the respondent has observed the change in climate. Of the total respondents perceived around 47% farmer have insured their livestock in Kaski district, 33% in Jhapa and 20 % in Dolakha district. Beside the proper vaccination, deworming, management and feeding of animals people are insuring their livestock assets due to uncertain in the climatic pattern and its consequences, this shows that livestock insurance is the one of the tool to mitigate with changing climate and climate relate hazard in livestock sector of Nepal.
Coactivation of agonist and antagonist muscles participates in the regulation of joint stiffness and postural instability. Alterations on muscle activity have been revealed as an important falling risk factor. It is unclear the effects, and age-related differences, of a prolonged demanding task on the muscular coactivation levels. We compared muscle activation amplitude and coactivation of the vastus medialis, biceps femoris, tibialis anterior, and gastrocnemius medialis from surface EMG in 16 young adults (age 21-33) and 8 elderly adults (age 66-72) while fast-walking at 70% of their maximum heart rate. Overall, the elderly demonstrated higher coactivation indexes than the young individuals. Ankle coactivation decreased in the first half of the swing phase, while coactivation at the knee increased in the latter half of the swing phase in our elders. Alterations of muscle activation and coactivation on the knee and ankle were more prominent close to landing and in the swing phase. Our results suggest that these alterations may suggest potential concerns with respect to the risk of falls.
Carazolol is a non-specific β-adrenargic reseptor blocking agent. It ıs structurally analogous to catecholamins, in that, when administered, it forms reversible bonds with β-adrenergic, however, induce adrenergic effects, and it inhibits the actions of the catecholamins in times of stres by saturing their sites of operation. The purpose of the research was to investigate the effects of carazolol on some serum enzymes, trace elements and cardiovascular status in sheep. Seven sheeps (age 6 months, 35 ± 10 kg) were used in this study. Carazolol administered by the intramuscular route at the dose of 0.01 mg/kg. Serum levels of urea, creatinin, ALT, AST, G-GT, LDH, T. protein, Ca, P, Mg, Cu, Fe, Zn, Se were investigated. Although all serum enzymes did not show any difference, serum Fe and Zn levels were decreased. Important results were obtained in electrocardiography (abnormal T wave and ST segment depression).
These results suggest that carazolol may increase incidence rate of myocardiyal ischemia risk in sheeps and it investigated by new researches.

Determination of the detector efficiency using volumetric cylindrical sources is very important in various scientific and industrial fields, especially in the field of quantitative analysis. To calculate the absolute activity of any sample, the full-energy peak efficiency (FEPE) of the detector is needed. By applying the efficiency transfer method, the FEPE of the detector would be determined easily without using the standard sources. This approach depends on two main factors. The first one, is the reference efficiency of the reference source, which is determined experimentally, and the second one, is the calculation of the effective solid angle ratio between the sample and the reference source geometries. This work introduces an empirical formula for calculating the second factor for using two different sizes of NaI(Tl) detectors. The validity of this empirical formula was successfully demonstrated by comparing the calculating values with the experimental values.
Investigation the influences of vitamin (vit) E over a period of 5 days on the pharmacokinetics of florfenicol after single and multiple oral administrations in broiler chickens. Total of 12 broiler chickens had been taken single and multiple oral administrations of florfenicol (30 mg/kg) alone or pre-treated with vit E (2 mg/kg). The serum concentrations of florfenicol were determined using microbiological assay with Bacillus subtilis (ATCC 25922) as a tested microorganism. The mean serum concentrations of florfenicol alone were markedly lower when compared with florfenicol pre-treated with vit E after single and multiple dosing. The peak serum concentrations (Cmax) were 5.9±0.46, 7.48±0.3 ug/ml, absorption half-life (t0.5ab) of 0.51±0.06, 0.71±0.1 h and elimination half-life (t0.5el) of 2.72±0.34, 3.34±0.5 after single florfenicol alone and florfenicol pre-treated with vit E respectively. While, after multiple dosing, (Cmax) were 7.4±0.3, 8.04±0.3 ug/ml, (t0.5ab) 0.82±0.04, 0.81±0.04 h and (t0.5 el) 3.77±0.2, 4.52±0.7 h after multiple dosing of florfenicol alone and florfenicol pre-treated with vit E respectively. In conclusion Vit E alter the disposition kinetics of florfenicol after single and multiple oral administrations as, vit E allows prolongation of the duration of action for more 24 and 48 h of the drug concentration in the serum indicated by prolonged elimination half-lives and MRT reflecting the importance of this combination for the drug duration in serum but the increase in the serum concentration of florfenicol increasing its efficacy not toxicity as florfenicol of wide safety margin so, it’s advisable for poultry farms owners to use this combinations.
Septic arthritis of the shoulder joint is rare and might affect around 3% of the general population [1]. A delay in diagnosis may increase morbidity and lead to bone and cartilage destruction [2]. Septic arthritis is an unusual complication of pregnancy and can progress to permanent arthropathy and disability [3].
Septic arthropathy in pregnancy requires multidisciplinary team involvement for prompt recognition and treatment to improve both maternal and fetal outcomes. High index of suspicion is vital when clinical and laboratory findings suggest septic arthritis. There are multiple predisposing factors reported previously for septic arthritis of the shoulder in pregnancy such as medical conditions, pyelonephritis and trauma. We report a 37 year old lady who presented at 26 weeks gestation with acute left shoulder pain and high temperature following minor left palm trauma. She also had left mastectomy with axillary clearance ten years earlier. She underwent arthroscopic wash out of her left shoulder joint and was covered with antibiotics with rapid improvement and recovery. We reinforce the importance of early multidisciplinary involvement when septic arthritis of the shoulder in pregnancy is suspected especially in women who have had previous mastectomy and axillary clearance which could be a predisposing factor for such a rare and serious joint condition in pregnancy.
In gamma-ray spectrometry, the analysis of the environmental radioactivity samples (soil, sediment and ash of a living organism) needs to know the linear attenuation coefficient of the sample matrix. This coefficient is required to calculate the self-absorption correction factor through the sample bulk. In addition, these parameters are very important because the unidentified samples can be different in the composition and density from the reference liquid sources which are usually used for efficiency calibration in the radioactive monitoring process. The present work is essentially concerned to introduce a mathematical method to calculate the linear attenuation coefficient without using any collimator. This method was based mainly on the calculations of the effective solid angle subtended by the source-to-the detector configurations, the efficiency transfer technique and the average path lengths through the samples itself. The method can be used as a tool for the calculation of the linear attenuation coefficient of unidentified materials with good facility to use it in the calibration process of γ-ray detectors, particularly in the study of soil samples. The results are compared with the data from NIST-XCOM to show how much the results are in close agreement and to give the validity of the approach.
Dry eye or keratoconjunctivitis sicca, is commonly seen in the dog. Veterinary ophthalmologists diagnose this aqueous tear deficiency using the Schirmer tear test (STT), but this measures tear production and does not indicate ocular surface pathology. The vital dye Rose Bengal is commonly used in the diagnosis of dry eye in human patients but until now has not been reported in veterinary patients. Here we corelate the degree of Rose Bengal staining with the STT value and find a reasonable association between dye staining of the ocular surface and tear production, although clearly other factors are also important in the genesis of ocular surface damage in dry eye.
The advancement of human researches and scientific activities in the field of diseases prevention and treatment, has not diminished the importance of sexually transmitted diseases (STDs). Despite the continuous efforts for prevention and control of them, many peoples suffers from STD with very considered wasted expenses for anybody and for community [1,2].
Background:Topical therapy with antimicrobial agents is used in otitis treatment. Due to increase of antibiotic resistance, new strategies are needed. Antiseptics are used but they may induce contact dermatitis. Natural antimicrobial peptides may represent future effective drugs.
Objectives:The objectives were to test the efficacy of an 11% lactoferricin otological solution (LCF) in bacterial and yeasts otic overgrowth and compare LCF with a commercial one containing chlorhexidine (CLX) 0.05%.
Materials and methods:Forty-one dogs diagnosed with bacterial or yeasts otitis overgrowths were included according to general good practice. They were randomly assigned to lactoferricin or chlorhexidine group for treatment. Otological solution were applied twice a day for a week and then daily for another week. Clinical and cytological score was assessed at day 1 and day 14. At the end of the study, the owners had to express an opinion on the overall efficacy of the products. Statistical analyses were performed using Wilkoxon’s test and T test for paired samples. Results in lesional and cytological score were significative with a p<0.05.
Results:Forty dogs completed the study. All cases, receiving lactoferricin or chlorhexidine, were successfully treated with clinical signs remission and regression of infection (p<0.05). The owners’ judgment was good in 87%, mild in 13% for LCF group. For CLX they scored good in 41%, mild in 24% and unuseful in 35% of cases.
Conclusions:Lactoferricin, an antimicrobial natural peptide, showed the same efficacy of chlorhexidine in the treatment of otitis characterized by bacterial or/and yeast overgrowth.
