Outbreak prediction of COVID-19 using Recurrent neural network with Gated Recurrent Units.

Respiratory infections corona virus 2-caused inflammatory disorders are CORONAVIRUS DISEASE 2019 (COVID-19) (SARS-CoV-2). A serious corona virus acute disease arose in 2019. Wuhan, China, was the first location to find the virus in December 2019, which has now been spreading all over the world. Recurrent neural networks, together with the use of LSTMs, fail to provide solutions to numerous issues (RNNs). So this paper has proposed RNN with Gated Recurrent Units for the COVID-19 prediction. This paper utilizes system, which was developed to assist nations (the Czech Republic, the United States, India, and Russia) combat the early stages of a newly emerging infection. For instance, the system tracks confirmed and reported cases, and monitors cures and deaths on a daily basis. This was done to allow the relevant parties to have an early grasp of the disastrous damage the lethal virus will bring. The implemented is an ensemble approach of RNN and GRU that work has computed the RMSE value for the different cases such as infected, cure and death across the four different countries.

Endocrine Complications of Noonan Syndrome beyond Short Stature.

Noonan syndrome (NS) is a diagnosis that is made clinically based on features including typical facies, congenital heart defects, short stature and developmental delay. Approximately 50% of the patients have identified mutations in the PTPN11 gene, and a smaller percentage of mutations have been reported in other genes such as SOS1, RAF1 and RIT1 Despite normal birth length, patients typically reach adult height below normal. Other than growth, endocrine complications of NS are not as commonly reported. These include possible pathology in thyroid function, pubertal development and bone metabolism. Some investigators have looked to see if genetic mutations in these patients could pose a risk for future endocrinopathies. This chapter reviews reports on endocrine dysfunction other than growth in patients with NS. The information is meant to enhance awareness in those providers who care for these patients to the possibility of other existing endocrinopathies. Most importantly, it supports and highlights the endocrinologist's role in the care of patients with NS.

Post-Translational Modifications in sperm Proteome: The Chemistry of Proteome diversifications in the Pathophysiology of male factor infertility.

BACKGROUND: The spermatozoa undergo a series of changes in the epididymis to mature after their release from the testis and subsequently in the female reproductive tract after ejaculation to get capacitated and achieve fertilization potential. Despite having a silenced protein synthesis machinery, the dynamic change in protein profile of the spermatozoa is attributed either to acquisition of new proteins via vescicular transport or to several post-translational modifications (PTMs) occurring on the already expressed protein complement. SCOPE OF REVIEW: In this review emphasis is given on the PTMs already reported on the human sperm proteins under normal and pathologic conditions with particular reference to sperm function such as motility and fertilization. An attempt has been made to summarize different protocols and methods used for analysis of PTMs on sperm proteins and the newer trends those were emerging. MAJOR CONCLUSIONS: Deciphering the differential occurrence of PTM on protein at ultrastructural level would give us a better insight of structure-function relationship of the particular protein. Protein with multiple PTMs could be used to generate the complex interaction network involved in a physiological function of a sperm. It can be speculated that crosstalk between different PTMs occurring either on same/ other proteins actually regulate the protein stability and activity both in physiological and pathological states. GENERAL SIGNIFICANCE: The analytical prospective of various PTMs reported in human spermatozoa and their relevance to sperm function particularly in various pathophysiological states, would pave way for development of biomarkers for diagnosis, prognosis and therapeutic intervention of male infertility.

Effect of hydrogen peroxide on rabbit urinary bladder citrate synthase activity in the presence and absence of a grape suspension.

PURPOSE: The etiology of obstructive bladder dysfunction includes free radical damage to mitochondria. Feeding rabbits a standardized grape suspension protects the ability of the bladder to contract and empty in part by preventing mitochondrial damage, thus maintaining smooth muscle and mucosal metabolism. The objective of the current study is to determine the direct effect of this grape suspension on the response of mitochondria to the oxidative effects of hydrogen peroxide. MATERIALS AND METHODS: Six male rabbits were anesthetized with sodium pentobarbital and the bladders excised. Four full thickness strips were obtained for contractile studies and the balance separated into smooth muscle and mucosa compartments by blunt dissection. The effect of hydrogen peroxide on the contractile response to field stimulation was quantitated. Each tissue was homogenized and the effects of increasing concentrations of hydrogen peroxide in the presence and absence of grape suspension on citrate synthase activity was determined. RESULTS: Citrate synthase activity was significantly higher in the mucosa than in the muscle. The grape suspension had no effect on control citrate synthase activity. However, the grape suspension provided significant protection of both smooth muscle and mucosal citrate synthase activity. CONCLUSIONS: These studies support the conclusion that the grape suspension provides direct protection of mitochondrial function.

Topical delivery of lycopene using microemulsions: enhanced skin penetration and tissue antioxidant activity.

Topical delivery of lycopene is a convenient way to supplement cutaneous levels of antioxidants. In this study, lycopene was incorporated (0.05%, w/w) in two microemulsions containing BRIJ-propylene glycol (2:1, w/w, surfactant blend) but different oil phases: mono/diglycerides of capric and caprylic acids (MG) or triglycerides of the same fatty acids (TG). Microemulsions containing MG and TG were isotropic, fluid, and clear, with internal phase diameters of 27 and 52 nm, respectively. Both MG- or TG-containing microemulsions markedly increased lycopene penetration in the stratum corneum (6- and 3.6-fold, respectively) and in viable layers of porcine ear skin (from undetected to 172.6 +/- 41.1 and 103.1 +/- 7.2 ng/cm(2), respectively) compared to a control solution. To assure that lycopene delivered to the skin was active, the antioxidant activity of skin treated with MG-containing microemulsion was determined by CUPRAC assay, and found to be 10-fold higher than untreated skin. The cytotoxicity of MG-containing microemulsion in cultured fibroblasts was similar to propylene glycol (considered safe) and significantly less than of sodium lauryl sulfate (a moderate-to-severe irritant) at 1-50 microg/mL. These results demonstrate that the MG-containing microemulsion is an efficient and safe system to increase lycopene delivery to the skin and the antioxidant activity in the tissue.
