Infertility caused by reproductive pathologies plays a significant role in animal breeding and could result in massive economic losses to livestock owners. Hence, this study was designed to allocate various pathological lesions in the female reproductive tract of she-camels ( ) slaughtered in Egypt and isolate the causative agents associated with those pathologies. A total of 500 genitalia of adult nonpregnant she-camels aged between 6 and 15 years old were collected from three slaughterhouses at the Giza Governorate, Egypt, from August 2017 to August 2019. The uterus, cervix, and vagina were examined pathologically and microbiologically. The uteri of 152 cases (30.4%), cervices of 24 cases (4.8%), and vaginae of 20 cases (4.2%) showed pathological abnormalities. The uterine inflammatory lesions were detected in 119 cases (23.8%), and the non-inflammatory lesions were detected in 58 cases (11.6%). Pathological changes of the cervix comprised 4.8%, whereas vaginal abnormalities represented 4%. The totalt to the environment and, consequently, human. In addition, attention should be paid toward the possibility of infected she-camels to transmit such infections to farm animals in contact. This study aimed to inspect the occurrence of ( ) in falcons from the central area of Saudi Arabia. Blood samples from 100 falcons species, including 55 , 22 , 13 and 10 , were collected from November 2018 to April 2019 and examined for by microscopic examination and nested PCR, targeting a cytochrome b ( ) gene. The prevalence was 1% by microscopic examination. The prevalence rate of was 1% by the microscopic method and 3% by PCR. Only was infected. In the sequence and phylogenetic analyses, the two sequences were 100% identical and closely related to the Lithuanian isolate with 99.35% identity. This study presents the first report of molecular detection and characterization of in from the Kingdom of Saudi Arabia.This study presents the first report of molecular detection and characterization of H. tinnunculai in F. cherrug from the Kingdom of Saudi Arabia. In recent years, lead (Pb) has arisen as a foremost contaminant due to overpopulation, rapid industrialization, and expansion that could contaminate the human food chain. LY3473329 clinical trial However, the correlation between the environmental contamination of Pb and its spatial transfer to the dairy products is still unmapped. In this paper, we intend to evaluate the concentration of environmental Pb and its spatial distribution in dairy feed and products in Narayangonj, a highly polluted district of Bangladesh. A total of 125 samples of soil, water, forage, and milk were collected from five upazilas (Narayangonj Sadar, Bondor, Rupgonj, Araihazar, and Sonargoan) of Narayangonj. The samples were digested by acid digestion, and Pb was detected by flame atomic absorption spectrophotometer and graphite furnace atomic absorption spectrometer. The bioconcentration factor of the samples was also calculated. In this study, 25% of the soil, 20% of the water, 5% of the forage, and 2% of the milk samples contained Pb at a variable levapted to cease the residue to the human food chain. The study of an embryosis is crucial in genetics for breed improvement and reproduction in livestock, identifying the causes of infertility, and stem cell application. Meanwhile, the problem of nucleic acid denaturation observed during embryo development is yet to be resolved. This study was set out to analyze the nucleic acid denaturation during the development of embryos. Using an fertilization-embryo in porcine, the cell development and apoptosis were evaluated by adding rapamycin by concentration to the TCM-199 containing 10% FBS or 10% porcine follicle fluid (pFF). Real-time PCR, zymography, DNA fragment, Western blot, and immunofluorescence analysis were also carried out to determine the development rate of inner cell mass in the fertilization-embryo. The findings indicated that the addition of rapamycin to the 10% pFF group during maturation led to an increase in the rates of cleavage and blastocyst development and the expression of active matrix metallopeptidase (MMP-9), while nucleic acid denaturation was suppressed. In other words, the addition of rapamycin was found to increase the expression of MMP-2 in the inner cell mass and trophoblast, while it inhibited apoptosis. The addition of rapamycin influences the regulation of apoptosis and MMPs, and based on this, it is presumed to have a positive effect on blastocyst development.The addition of rapamycin influences the regulation of apoptosis and MMPs, and based on this, it is presumed to have a positive effect on blastocyst development. The aim of this research is to investigate the relationship level of oxytocin released and the tactile stimulation of the cervix in Holstein cattle from the northwestern arid regions in México. The cervixes of 10 Holstein Friesian dairy cows in mid-lactation were manually stimulated for 60 sec. Oxytocin released in the blood was analyzed before and after stimulation. The enzyme-linked immunosorbent assay was used in the analysis to make oxytocin detectable by spectrometry techniques and by converting the luminescence absorbance of each sample into pg per mol. The study revealed that tactile stimulation of the cervix increased oxytocin levels. The highest increase in oxytocin level was 10,940.8222 pg/mol, while the lowest increase in oxytocin level was 1,830.94254 pg/mol. Besides, the milk production by tactile stimulation of the cervix had a higher milk yield and a value of 9.4 × 10 ( < 0.05) in comparison to the monthly average without tactile stimulation. Tactile stimulation of the cervix activates the Ferguson reflex and increases the oxytocin released in the blood and increases the milk released from the alveolar glands.Tactile stimulation of the cervix activates the Ferguson reflex and increases the oxytocin released in the blood and increases the milk released from the alveolar glands. Selenium (Se), as the form of selenite, is commonly supplemented in poultry diet, which has low bioavailability and high toxicity. Here, we compared the effects of the supplementation of the diet with Se nanoparticles (nano-Se) on the growth, sexual behavior, and reproductive performance (gonad size, sperm quality traits, and plasma testosterone levels for males and egg production for females) of Japanese quail ( ). Quail chicks ( = 300) aging 14 days were divided into three groups Group 1 (basal diet and Se at 0.2 mg/kg ration), Group 2 (basal diet and nano-Se at 0.2 mg/kg ration), and Group 3 (basal diet and nano-Se at 0.1 mg/kg ration). Several parameters relating to body weight and egg were measured. Sexual behaviors of the birds were observed by continuous visual scanning. The sperm viability, sperm morphology, and concentration of spermatozoa were determined after staining and microscopic examination. The plasma testosterone levels were determined by indirect enzyme immunoassay assay. The Se concentrations in the testicular, ovarian, and ration samples were measured by flame emission atomic absorption spectrophotometer.
