Being a multipurpose animal goat can produce meat, milk and hide. India has a good number of Black Bengal goat populations, which has an important role in the lives of local goat rearers. The goal of the present study is to find out the effects of changing seasons on some biochemical parameters ofBlack Bengal goat (Capra aegagrushircus) in two different agro-climatic zones in India. The highest mean value of temperature (42.6 ± 1.5 ºC) has been reported during the month of April or May in the season of pre-monsoon in Purulia. However, the lowest value of temperature (8.6 ± 0.9 ºC) has been reported during the month of December or January in the season of post-monsoon again in Purulia. The parameter studied here are blood pH, blood glucose level, concentration of Hb, RBC count, PCV, MCV, MCH and MCHC. Data has analyzed for the effect of seasonal variation among in both the regions and the current findings implies that not only seasonal variation but the regional variation also influence the major biochemical responses of goats.
A 67-year-old lady underwent electrophysiologic testing because of recurrent palpitations. Atrio-His (AH) and His-ventricular intervals measure 98 and 44 ms, respectively. Retrograde conduction was midline and decremental. Dual atrioventricular (AV) nodal physiology was present and programmed atrial extrastimulation induced a narrow complex tachycardia (NCT) after a critical AH delay.Figure 1 shows the NCT with 2:1 and 4:3 VA Wenckebach. The differential diagnosis of which includes AV nodal re-entrant tachycardia (AVNRT) with upper common pathway block, junctional tachycardia (JT) with nodoatrial block, and orthodromic nodofascicular (NF) re-entrant tachycardia with nodoatrial block.Figure 2 shows response of the NCT to an early spontaneous APB, which would have either reset JT 1 or alternatively terminated
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
