Erectile dysfunction (ED) is a common disorder whose prevalence increases with age. Over time a strong correlation between erectile dysfunction and cardiovascular disease has been established as the result of the same pathophysiological process: endothelial dysfunction and atherosclerosis. Because small vessels of the penis can be affected by atherosclerotic plaque earlier than coronary arteries, carotids or femoral arteries, men often have symptoms of ED long before the signs of cardiovascular disease appear. For this reason, ED can act as a marker of early atherosclerosis that predicts the onset of cardiovascular disease at a later time.

In order to better understand some neurologic degenerative process is fundamental to use also an evolutionary approach of vertebrates and especially in mammalians. Aim of this work is to verify if an objective measure of brain wasting system can help in this kind of disease. Imaging can help in measuring efficiency of brains wasting system in the various subject. The brain glymphatic systems is well studied today but an accurate measure of the real efficiency of the system is needed. It is relevant so to submit to researcher a working methods strategy to measure this parameter to verify if possible, to use the brain glymphatic system as new therapeutics pathway.

Nobody doubts that mathematics plays a crucial role in medical achievements. It is certain that is being mainly used in statistics and physics for biomedical problems [1]. For sure that we have already heard about how mathematics can improve the anticancer arsenal [2]. Quantitative genetics have triggered a giant potential in medical care [3,4]. And mathematical algorithms, provided by artificial intelligence, continuously boost new therapeutic paradigms [5,6]. Nonetheless, one cannot ignore the ability of mathematics for analyzing ideas.

The normal levels of thyroid hormones (THs; thyroxine, T4 & 3,5,3′-triiodo-L-thyronine, T3) are necessary for the normal development [1-48], particularly the fetal and neonatal cardiac growth and development [49]. The actions of THs are facilitated genomically by thyroid receptors (TRs, α and β) and non-genomically at the plasma membrane, in the cytoplasm and in cellular organelles [4,49-55], by stimulation of Na+, K+, Ca2+ and glucose transport, activation of protein kinase C (PKC), protein kinase A (PKA) and mitogen activated and protein kinase (ERK/MAPK) [4]. In addition, the transport of T4 and T3 in and out of cells is controlled by several classes of transmembrane TH-transporters (THTs) [56], including members of the organic anion transporter family (OATP), L-type amino acid transporters (LATs), Na+/Taurocholate cotransporting polypeptide (NTCP), and monocarboxylate transporters (MCTs) [4,49,57,58]. Adding additional complexity, the metabolism of T4 and T3 is regulated by 3 selenoenzyme iodothyronine deiodinases (Ds: D1, D2 and D3) [59-61]. On the other hand, the congenital hypothyroidism can cause the following [49,62-64], (1) congenital heart diseases; (2) diastolic hypertension; (3) reduced cardiac output, stroke volume and a narrow pulse pressure; (4) dilatation and overt heart failure; (5) elevation in the systemic vascular resistance [65-68]. Similarly, the chronic hyperthyroidism can cause the following [49,64]: (1) cardiac hypertrophy; (2) increase in the cardiomyocyte (CM) length rather than width; (3) noticeable diminution in systemic vascular resistance; (4) elevation in the cardiac contractility; (5) systolic hypertension; (6) increase in the cardiac output, venous volume return, blood volume and pulse pressure; and (7) reduction in the systemic vascular resistance [49,69]. T3-therapy can induce DNA synthesis and cardiomyocyte proliferation, and improve the cardiac contractility; though, this action is as still unidentified [49,70-74].

Background: Colorectal cancer progresses without any symptoms early on, or those clinical symptoms are very discrete and so are undetected for long periods of time. The case reported is an unusual presentation of colorectal cancer. Case Report: A 60 year old man presented with right sided abdominal swelling. On examination, a well-defined, firm, tender swelling was noted. Computed tomography confirmed the presence of a mass arising from the right colon with infiltration of the right lateral abdominal wall and adjacent collection. An exploratory laparotomy with drainage of the subcutaneous abscess, resection of ascending colon, and ileotransverse colon anastomosis was performed. Conclusion: A differential diagnosis of carcinoma colon should be considered when an elderly patient presents with abdominal wall abscess accompanied by altered bowel habits or per rectal bleeding, even if there are no other significant clinical symptoms and a thorough investigative work up is required to confirm the diagnosis, to avoid untimely delay in treatment, and reduce mortality.

The Positive Regulatory Domain (PRDM) protein family gene is involved in a spectrum variety of biological processes, including proliferation, differentiation and apoptosis: its member seem to be transcriptional regulators highly cell type and tissue peculiar, towards histones modifications or recruitment of specific interaction patters to modify the expression of target genes. In this study we analyzed the expression profile of different member of PRDM gene family focusing our attention on the role of PRDM2, PRDM4 and PRDM10 genes in mouse C2C12 cell line, during the differentiation of myoblasts into myotubes and speculate about the role of the protein Retinoblastoma protein-interacting zinc finger protein 1-RIZ1, coded by PRDM2 gene, as a regulator of the proliferation/differentiation switch. Results showed a reduction of PRDM2, PRDM4 and PRDM10 expression level during the commitment of the differentiation of myoblasts into myotubes. The RIZ1 silencing stimulated myoblasts differentiation, similar to the effect of serum deprivation on these cells, associated with an increase of Myogenin expression level, which is considered to be involved in the differentiation of myoblasts into multinucleated myotubes. As demonstrated by chromatin immunoprecipitation experiments, RIZ1 is associated with Myogenin promoter in proliferation condition and after 24h from differentiation induction, negatively controlling therefore Myogenin expression. Moreover RIZ1 silencing induced a reduction in PRDM4 and PRDM10 expression levels leaving us to speculate that the PRDM genes have a redundant role and they are hierarchically organized.

We know that Corona Virus develops in animals, birds and humans’ body. Now it is a pandemic and many people are dying with each passing day and a number of patients are increasing every hours. If we do not control it then it is dangerous for humanity. As we know that incubation period for COVID-19 is 1 to 14 days and it’s live in the environment for 12 to 14 hours. The only solution to spread of virus is by social distancing. As we know that it affects person with low immunity so it is advised for all people to have balance diet, exercise daily and spend time in meditation for increasing immunity. I want to share a natural method to develop and increase the immunity power by the bile juice of animals, birds and we can try for corona virus too.

In the late of 2019, there is an outbreak of novel coronavirus disease (COVID-19) in Wuhan, China. The patients appear respiratory symptoms, fever, and cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death. A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans and is transmitted mostly via droplets or contact. People of all ages are susceptible to the virus. Up to the middle of February 2020, the number of infected persons in China is over 65,000. The case fatality rate was 2.38%, and elderly men with underlying diseases were at a higher risk of death [1].

Colon cancer (CC) screening is important for diagnosing early stage for malignancy and therefore potentially reduces mortality from this disease because the cancer could be cured at the early disease stage. Early detection is needed if accurate and cost effective diagnostic methods are available. Mortality from colon cancer is theoretically preventable through screening. The Current screening method, the immunological fecal occult blood test, FOBTi, lacks sensitivity and requires dietary restriction, which impedes compliance. Moreover colonoscopy is invasive and costly, which decreases compliance, and in certain cases could lead to mortality. Compared to the FOBT test, a noninvasive sensitive screen that does not require dietary restriction would be more convenient. Colonoscopy screening is recommended for colorectal cancer (CRC). Although it is a reliable screening method, colonoscopy is an invasive test, often accompanied by abdominal pain, has potential complications and has high cost, which have hampered its application worldwide. A screening approach that uses the relatively stable and nondegradable microRNA molecules when extracted from either the noninvasive human stool, or the semi-invasive blood samples by available commercial kits and manipulated thereafter, would be more preferable than a transcriptomic messenger (m)RNA-, a mutation DNA-, an epigenetic-or a proteomic-based test. That approach utilizes reverse transcriptase (RT), followed by a modified quantitative real-time polymerase chain reaction (qPCR). To compensate for exosomal miRNAs that would not be measured, a parallel test could be performed on stool or plasma’s total RNAs, and corrections for exosomal loss are made to obtain accurate results. Ultimately, a chip would be developed to facilitate diagnosis, as has been carried out for the quantification of genetically modified organisms (GMOs) in foods. The gold standard to which the miRNA test is compared to is colonoscopy. If laboratory performance criteria are met, a miRNA test in human stool or blood samples based on high throughput automated technologies and quantitative expression measurements currently employed in the diagnostic clinical laboratory, would eventually be advanced to the clinical setting, making a noticeable impact on the prevention of colon cancer.

Inflammation is a complex biological reaction induced by the alteration of tissue homeostasis, which occurs in response to the presence of a biological, chemical or physical agent in the body [1]. The acute inflammatory response is composed of an elaborate cascade of both proinflammatory and anti-inflammatory mediators, and balance between these mediators often determines the outcome after injury [2]. Generally during acute inflammation, cellular and molecular events and interactions reduce the risk of eventual injuries or infections. However, acute inflammation can become chronic, contributing to a variety of chronic inflammatory diseases [3]. Major micro circulatory events that occur during the inflammatory process include changes in vascular permeability, leukocyte recruitment and accumulation, and inflammatory mediator’s release [4].
