Interferon-τ (IFNT), produced in ruminants by embryonic trophoblastic cells before implantation, is involved in the maternal recognition of pregnancy. It is a pleiotropic molecule that alters the synthesis of endometrial proteins and inhibits the proliferation of some cells. The present study investigated the effects of recombinant bovine IFNT on the development of early-stage bovine embryos and the molecular mechanism underlying this effect. This study demonstrated that expression of mRNA encoding type I IFN receptor subunits was detectable from d 4 to 8 in in vitro fertilized (IVF) bovine embryos. A considerable number of IVF (n = 1,941) and parthenogenetic activated (n = 1,552) bovine embryos demonstrated that supplementing the culture medium with IFNT (100 ng/mL) produced a greater percentage of blastocysts, and the total cell number within the resulting blastocysts was higher. In addition, IFNT upregulated the expression levels of both mRNA and protein for connexin 43 (GJA1) and E-cadherin (CDH1) and expression levels for granulocyte-macrophage colony-stimulating factor and insulin-like growth factor 2 mRNA but not for their proteins in d 8 embryos. However, IFNT inhibited mRNA expression for leukemia inhibitory factor (LIF), LIF receptor α, and the sodium/potassium-transporting ATPase subunit β-1. We concluded that IFNT promoted the development of bovine embryos by upregulating the expression of GJA1 and CDH1. Thus, supplementing embryo cultures or transfer medium with IFNT may stimulate embryo development and improve embryo transfer efficiency.

The purpose of this study is to check out the spread rate of Hepatitis B Virus in the districts of Mardan and Charsadda, KPK Pakistan. As we know that Hepatitis results in damaging liver tissues, so it is one of the serious threats to the human health across the world. Hepatitis can give rise to acute and chronic infection which give rise to Liver cancer or Liver cirrhosis. It may be transfer from one person to another. Its transmission routs are oral, fecal and parental. The purpose of this paper is to check and judge health condition. Blood serum was collected from Mardan Medical Complex, Mardan and District Head Quarter, Charsadda. The paper was design to calculate anti-HBV antibody positive patients with ICT(immune-chromatography technique)based detection among various patients in MMC Mardan and DHQ hospital Charsada and from various regions of Mardan and Charsadda, KPK Pakistan.  Total of 10852 patients of HBV in Charsadda and 14168 patients of HBV in Mardan. The blood samples were collected from Oct 2017 to May 2018 from both districts of KPK. The method for testing blood sample was ICT (immune chromatography technique). Our study about 10852 patients in district Charsadda who were at the risk of HBV infection, 103 were screened positive with the prevalence ratio of 0.949%. On the other hand, 14168 patients`s samples were collected in district Mardan, among them 149 were detected positive and ratio of prevalence is 1.051%. According to the above study the ratio of prevalence is lower in Charsadda as compare to Mardan

Kari sheep inhabiting the Chitral district of Pakistan show variation in gestation length. In this study, we have analyzed the genetic differences between the three subtypes of Kari sheep (based on variation in gestation length) using microsatellite markers. Kari sheep samples were collected from their breeding tract and were characterized for gestation length and genetic diversity using microsatellite markers. A total of 78 Kari ewes were grouped into three categories based on gestation length (GL), i.e., Kari–S (with a shorter GL), Kari–M (with a medium GL), and Kari–L (with a longer GL). DNA from these samples was used to amplify 31 ovine–specific microsatellite loci through PCR. Of the total 78 Kari specimens, 24 were grouped in Kari–S (GL = 100.7 ± 1.8), 26 were from the Kari–M subtype (GL = 123.1 ± 1.0), and 28 were Kari–L (GL = 143.8 ± 1.5). Microsatellite analysis revealed an association of genotypes at two marker sites (MAF214 and ILSTS5) with variation in GL. A total of 158 alleles were detected across the 22 polymorphic loci with an average of 7.18 alleles per locus. Unique alleles were found in all three subtypes. The highest number of unique alleles was observed in Kari–L (15), followed by Kari–S (10) and Kari–M (8). The results indicated that Kari–S is a genetically distinct subtype (with higher genetic differentiation and distance) from Kari–M and Kari–L. The genetic uniqueness of Kari–S is important for further exploration of the genetic basis for shorter gestation length, and exploitation of their unique values.
