Electrocardiogram of Clinically Healthy Mithun (Bos frontalis): Variation among Strains
A study was conducted to establish the normal electrocardiogram in four different genetic strains of mithun (Bos frontalis). Electrocardiography, cardiac electrical axis, heart rate, rectal temperature and respiration rate were recorded in a total of 32 adult male mithun of four strains (=8 each). It was found that the respiration and heart rates were higher (<.05) in Manipur than other three strains. Amplitude (<.05) and duration of P wave and QRS complex differed (<.01) among the strains. Mizoram strain had the highest amplitude and duration of P wave and QRS complex. On the other hand, higher (<.05) amplitude and duration of T wave were recorded in Arunachalee and Mizoram strains. The mean electrical axis of QRS complex that were recorded for Arunachalee and Manipur strains were similar to that reported for other bovine species; whereas the electrical axis of QRS for Nagamese and Mizoram strains were more close to feline and caprine species, respectively. In conclusion, electrocardiogram of mithun revealed that the amplitude and duration of P wave, QRS complex and T wave were different among four different genetic strains of mithun and the electrical axis of QRS complex for Nagamese and Mizoram mithuns are dissimilar to bovine species
sperm cryopreservation glycerol mithun
Not AvailableThe effect of concentration and addition method of glycerol on the quality of cryopreserved mithun (Bos frontalis) spermatozoa was investigated. Semen samples were collected from five healthy mithun bulls through rectal massage method and cryopreserved in liquid nitrogen. The samples were diluted in Tris–egg yolk–glycerol extender, equilibrated for 4 h at 4 °C and loaded into 0.50‐ml straws. The straws were then frozen in liquid nitrogen vapour for 10 min and finally plunged into liquid nitrogen for storage. The required amount of glycerol was added into the diluted samples either in a single dose (3%, 4%, 5%, 6% or 7%; added at 37 °C immediately before equilibration) or in split doses (5%, 6% or 7%; the total amount was divided into four equal parts, and a part was added at 37 °C immediately before equilibration, and the remaining parts were added subsequently at 1, 2 and 3 h of equilibration at 4 °C). In the single‐dose addition method, following freeze‐thawing, greater (p < 0.05) motility (%) and proportion of live spermatozoa with intact acrosome (LSIA, %) in 5% glycerol (40.6 ± 1.7 and 43.4 ± 1.8 respectively) and lesser (p < 0.05) total morphological abnormalities (%) in 5% (14.1 ± 0.8) and 6% (13.7 ± 1.0) glycerol were observed compared to the other glycerol concentrations. In the split‐dose addition method, following freeze‐thawing, greater (p < 0.05) motility (%) and LSIA proportion (%) were found in 5% (50.2 ± 1.9 and 53.3 ± 1.8 respectively) compared to 6% or 7% glycerol, but the total morphological abnormalities were not different among the glycerol concentrations. In addition, in all the glycerol concentrations, better (p < 0.05) post‐freeze‐thaw motility and LSIA proportions were observed when glycerol was added in split doses compared to a single dose. In conclusion, Tris–egg yolk extender with 5% glycerol added in split doses was found most suitable for cryopreserving mithun sperm.Not Availabl
Air Quality-Lung Cancer Data
Data comes from two different sources. Population-based lung cancer incidence rates for the period 2010-2014 (most updated data) were abstracted from National Cancer Institute state cancer profiles (Schwartz et al. 1996).This national county-level database of cancer data is collected by state public health surveillance systems. The domain specific county level environmental quality index (EQI) data for the period 2000-2005 were abstracted from United States Environmental Protection Agency (USEPA) profile. Complete descriptions of the datasets used in the EQI are provided in Lobdell’s paper (Lobdell 2011). Data were merged based on the Federal Information Processing Standards (FIPS) code. Out of 3144 counties in United States this study has available information for 2602 counties: Data was not available for four states namely Kansas, Michigan, Minnesota and Nevada due to state legislation and regulations which prohibit the release of county-level data to outside entities, county whose lung cancer mortality information is missing were omitted from the data set, the Union county, Florida is an outlier in terms of mortality information which was deleted from the data set, in the process of local control analysis this study experiences two (cluster 28 and 29) non-informative clusters (non-informative cluster is one for which either treatment or control group information is missing). For analysis, non-informative clusters information was deleted from the data set.
Three types of variables are used in this study: (i) lung cancer mortality as an outcome variable (ii) binary treatment indicator is the PM2.5 high (greater than 10.59 mg/m3) vs. low (less than 10.59 mg/m3) (iii) three potential X confounder for clustering namely land EQI, sociodemographic EQI and built EQI. For each index, higher values correspond to poorer environmental quality (Jagai et al. 2017). As PM2.5 is one of the indicators for measuring air EQI, that is why we do not consider the air EQI to avoid confounding effects
Research on Freezability of Spermatozoa by Use of Various Concentrations of Glycerol in Mithun (Bos frontalis) Semen Cryopreservation
A study was conducted to investigate the various glycerol concentrations on freezability of mithun semen. The present study was conducted in semen production laboratory, ICAR-NRC on Mithun, Medziphema, Nagaland, India. A total of 20 ejaculates were collected from apparently healthy mithun bulls (n=6) by trans-rectal massage method. These ejaculates were extended with tris–egg yolk-citrate-glycerol diluent (TECG) and 5, 6 and 7% (v/v) glycerol, respectively were used as a cryoprotectant. Extended semen was equilibrated, cryopreserved and stored in liquid nitrogen with standard protocols. Semen quality parameters (SQPs) such as percentage of forward progressive motility, viability (Eosin Nigrosin staining), acrosomal integrity (Giemsa staining) and total morphological abnormality (Eosin Nigrosin staining) were estimated with standard procedure at different stage of preservation and with different concentration of the glycerol. The result revealed that these semen quality parameters were differed non-significantly among the three experimental groups at immediately after final dilution (Stage: 1) and differed significantly (p<0.05) at 4 hrs of equilibration (Stage: 2) and at post thawing stage (Stage: 3) of semen cryopreservation. Further, 5% glycerol treated group has shown significantly (p<0.05) higher values of motility and live with acrosomal integrity and lower value of total morphological abnormality than in 6% or 7% glycerol treated groups. Based on the result, it was concluded that 5% glycerol was best for the TECG diluent for preserving mithun semen in liquid nitrogen

Not AvailableStudies conducted on 106 mithun at the National Research Centre on Mithun and
66 free-ranging mithun in Nagaland, India, revealed an infection rate with
bluetongue virus of 86%, using a commercially available competitive enzymelinked
immunosorbent assay. Animals were grouped according to their age: 36 of
1 to 2 years of age, 50 of 2 to 4 years of age and 86 aged 4 years and over. The
highest infection rate (98%) was found in mithun > 4 years old and the lowest
(58%) in those 1 to 2 years old. No statistically significant difference was
observed between infection rates of males (89%) and females (85%). The
infection rate was higher (95%) in free-ranging mithun than in mithun kept under
a semi-intensive system (80%). This is the first report of serological evidence of
antibodies to bluetongue virus in mithun. The possible role of vectors in the
epidemiology of bluetongue virus infection in mithun is discussed brieflyNot Availabl
