Forensic analysts are more than ever facing challenges upon conducting their deep investigative analysis on digital devices due to the technological progression. Of these are the difficulties present upon analyzing web browser artefacts as this became more complicated when web browser companies introduced private browsing mode, a feature aiming to protect users’ data upon opening a private browsing session, by leaving no traces of data on the local device used. Aiming to investigate whether the claims of web browser companies are true concerning the protection private browsing provides to the users and whether it really doesn’t leave any browsing data behind, the most popular desktop browsers in Windows were analyzed after surfing them regularly and privately. The results shown in this paper suggest that the privacy provided varies among different companies since evidence might be recovered from some of the browsers but not from others.

Subungual exostosis (SUE) is a benign phalangeal tumor of an osteocartilaginous nature [1]. SUE is most commonly diagnosed in children and young adults; most of these lesions are located in the big toe, although they can occur (albeit infrequently) in other toes. We report five observations of SUE described in young children under 10 years and discuss the particularities of this pathology in the pediatric population.

The economic inequalities associated with suicide risks among 50 states in the United States were identified in this paper to form the dynamic panel data set from 1981 to 2016. The effects of growing income inequalities on suicides in the Unites States were estimated using the Arellano–Bond method. This paper is the first to associate the social inequalities with suicides using the state-level dynamic panel data in America. It is found that the change of unemployment rates significantly and positively impact the changes of the overall suicides rates, female and male suicides rates. The changes of Top 10% income index are uniformly positive to the change of female, male and overall state-level suicide rates. The Gini index has positive correspondence within the overall and female groups, along with the insignificantly vague evidence within the male groups. The potential endogeneity problem inferring from the fixed effect estimation has been also investigated accordingly. JEL Classification: A13, A14, I18. 

The major use of alternative light sources (ALS) in the evaluation of bloodstains has been primarily focused on detection of whole blood, with relatively little attention to visualization of blood serum. Serum may become separated from blood pools during clotting, and because it is relatively invisible on certain backgrounds, go undetected by a perpetrator attempting to clean up a crime scene. Recently, Ultraviolet 365 (UV 365) was shown to be an effective tool in blood evaluation, useful for detection of even minute quantities of blood serum. Here the effects of environmental conditions on blood serum stain appearance were evaluated, including temperature, pH, protease sensitivity, solubility, and aging. Interestingly, it was found that the UV fluorescence of serum increases upon exposure to heat, which was accompanied by color changes under visible light and decreased solubility in multiple solvents. The efficiency of visualization of serum stains was somewhat variable, depending on the type of material on which it was dried. Finally, the current study documents the effect of heating on formation of fluorescent serum halo rings in dried bloodstains. Taken together, these data demonstrate that blood serum detection may be affected by certain conditions that influence its visualization under both visible and UV light.

Growing evidence supports the hypothesis that endothelial cell-derived microparticles (MPs) might contribute to the pathogenesis of cardiovascular (CV) disease. Endothelial cell-derived MPs play a pivotal role in the regulation of the endogenous repair system, thrombosis, coagulation, inflammation, immunity and metabolic memory phenomenon. There is evidence that the MPs are secreted actively accompanied to other regulatory molecules. All these actively synthetizing and secreting factors include proteins, adhesion and intercellular signal molecules, peptides, lipids, free DNAs, microRNAs, and even microparticles (MPs) are defined as cellular secretome. The proteomic profile of secretome is under tightly control of genetic and epigenetic mechanisms, which may altered a secretion of the proteins involved into MPs’ organization. Finally, this may contribute the modification of MP’s after their secretion and throughout transfer to the target cells. As a result, communicative ability of endothelial cell-derived MPs may sufficiently worse. Subsequently, cross talk between some components of secretome might modulate delivering cargos of MPs and their regenerative and proliferative capabilities via intercellular signaling networks. The aim of the review is to discuss the effect of various components of secretome on MP-dependent effects on endothelium.

Mast cells play a central role in the genesis and modulation of allergic and inflammatory responses. The general aim of the present work was to study the interaction between mast cells and the most common additives approved for use in foods. Dose-response studies about the effect of the main food additives (tartrazine, sodium bisulphite and sodium benzoate) on mast cell degranulation were carried out. Rat peritoneal mast cells were incubated with: 1) buffer solution or 2) stimulus. The stimuli were tartrazine, sodium benzoate, sodium bisulphite and the calcium ionophore A23187. A23187 was used as a reference mast cell secretagogue. Different doses and combinations of food additives were used. The viability of the mast cells was evaluated with trypan blue. In the incubation solutions, the release of β-hexosaminidase was quantified by colorimetric reaction and ELISA plate reader. The remaining β-hexosaminidase concentration (not released) was studied in the cells after the incubations, and morphology of the mast cells was analyzed by light microscopy with toluidine blue stain. The food additives tartrazine, sodium benzoate and sodium bisulphite did not stimulate the release of β-hexosaminidase from mast cells at any of the concentrations used. In contrast, tartrazine at concentrations of 0.1 μM and 1 μM, and sodium benzoate and sodium bisulphite at concentrations of 0.1 μM, 1 μM, 10 μM and 100 μM, significantly inhibited the basal release of β-hexosaminidase from mast cells. Considering these findings, we decided to determine the effect of these additives on the degranulation of mast cells induced by the calcium ionophore A23187. Sodium bisulphite inhibited mast cell activation induced by the calcium ionophore A23187 in this experimental model. The present study demonstrates that food additives of usual permitted use do not stimulate basal degranulation of mast cells in an in vitro model of peritoneal mast cells and that the additive sodium bisulphite inhibit mast cell activation induced by intracellular calcium increase. This food additive could represent an interesting alternative in the prevention of pathologies mediated by mast cells, as well as in the field of nutritional biochemistry.

The emergence and establishment of anthropological genetics as an interdisciplinary science is primarily, associated with the development of new genomic technologies. Precision genetic testing on the one hand, and the rapidly increasing number of genetic investigations on the other, have created a set of bioethical dilemmas for genetic and epidemiology research. Such research deals with persons who have the right to the protection of their personal information and confidentiality, and also concerns collective (village, region, ethnic group, state) consciousness, ethnic identity, and traditional culture, i.e., so called “ethnic pride”. In this regard, taking into consideration the results of ongoing field research, we make some recommendations for better management of relationships with individuals and communities and the preparation of questionnaires and informed consent forms that will facilitate similar research projects, especially in such an ethnically, linguistically and culturally diverse region such as the Caucasus.

The objective of this paper is to emphasis the AngioCT features of carotid dissection/mural hematoma. The image show an internal carotid artery with narrowly eccentric lumen surrounded by a crescent-shaped hypodense mural thickening, with a visibly enhancing vessel wall. The carotid hematoma is a hypodense mural thickening that leads to expansion of the arterial wall, compression of the lumen and release of thrombogenic factors by intimal damage. Hematoma between the intima and media causes vessel expansion diameter and a narrow eccentric lumen. Peripheral hyper density is due to the contrast enhancement of the vasa vasorum in the adventitial layer. The physician should be familiar with the imagiologic features of carotid arterial disease, due to the diferent treatment options.

It is estimated that even up to 30% of buildings worldwide may be the subject of complaints connected with the quality of indoor air. Potential sources of air pollution can be both organic and inorganic particles. This article focuses on biological air pollutants from living and dead biological sources, especially those connected with fungi. Fungi found in the indoor air of domestic dwellings in a large extent are similar in their species composition to those found on the outside of the building. Microorganisms enters into the buildings during the airing of rooms or through the different slots and can develop on the surfaces of various materials. Intensively develops in a poorly ventilated, damp and dusty environments. For this reason the exposure to the indoor air pollution might be stranger for inhabitants than the expose to the impurities of the outdoor air. Presence of fungi in domestic dwellings can be very danger because of most often is associated with allergic reactions, mycotoxins, volatile organic compounds or even with fungal infections.

Venous Thromboembolism (VTE) is a multifactorial disease that is influenced by individual genetic background and various environmental factors, high altitude (HA) being the one. HA exposure may cause release of several damage associated molecular patterns (DAMPs), which act as ligand for various immune receptors. Previous studies on western population involving SNPs analysis of TLRs demonstrated that TLRs are involved in development and progression of several cardiovascular diseases. But, no such study has been done in Indian population in context of HA exposure. TLRs, being receptors play a significant role in manifestation and elimination of diseases by recognition of specific ligands and downstream signal transduction therefore; the genetic variation in TLRs could be implicated for imparting varying response of individuals to discrete diseases. Therefore, in accordance with it, in present study changes in protein structures of TLR2 and TLR4 due to presence of SNP were accessed by in-silico tools to observe whether the mutation has effect on protein structure and integrity which further influencing its function. The results showed that SNP harbouring protein has decreased functional pockets, thus may be protective for disease. Taking this lead further to genotypic level, first time association between Toll-like receptor genes polymorphism and risk of high altitude induced venous thrombosis is analyzed in Indian population by PCR RFLP method. Though the result showed initial trend that TLR2 and TLR9 SNP are monomrphic in distribution and for TLR4 there was no significant difference in distribution of SNP between healthy and HA-DVT group, these SNPs have potential to be used as susceptibility markers if studied in large population size. 

Transglutaminases are a family of Ca2+-dependent enzymes which catalyze post-translational modifications of proteins. The main activity of these enzymes is the cross-linking of glutaminyl residues of a protein/peptide substrate to lysyl residues of a protein/peptide co-substrate. In addition to lysyl residues, other second nucleophilic co-substrates may include monoamines or polyamines (to form mono-or bi-substituted/crosslinked adducts) or -OH groups (to form ester linkages). In absence of co-substrates, the nucleophile may be water, resulting in the net deamidation of the glutaminyl residue. Transglutaminase activity has been suggested to be involved in molecular mechanisms responsible for both physiological and pathological processes. In particular, transglutaminase activity has been shown to be responsible for human autoimmune diseases, and Celiac Disease is just one of them. Interestingly, neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, supranuclear palsy, Huntington’s disease and other polyglutamine diseases, are characterized in part by aberrant cerebral transglutaminase activity and by increased cross-linked proteins in affected brains. Here we describe the possible molecular mechanisms by which these enzymes could be responsible for such diseases and the possible use of transglutaminase inhibitors for patients with diseases characterized by aberrant transglutaminase activity.

Hemangiomas are known as congenital vascular malformations that can affect almost any organ or tissue, with the liver being the most common intra-abdominal organ to be involved. It is well known that hemangiomas are the most common benign tumours of the liver, and develop in about 4-20% of people, mainly young adult females. Recently, due to the dramatic rise in the use of imaging studies for different purposes, a parallel increase in the incidence of these tumours has been noticed. Most liver hemangiomas are small (less than 4cm in diameter), asymptomatic and found incidentally during abdominal operation for other indication or on radiologic studies. Giant liver hemangioma is defined as hemangioma with a diameter of more than 5cm. This unique and uncommon type of haemangioma usually poses therapeutic challenges for the treating physician, especially hepatic surgeons, due to the unclear natural history, and due to the risk of life threatening complications is yet to be established. While it is already proved by several studies that conservative management of giant hepatic hemangioma is safe, it is not known whether observation of the extremely large hepatic hemangioma (tumours larger than 10cm) is safe as well. The aim of this article is to review the English literature to find out if conservative management of the extremely giant liver hemangioma is safe and can be recommended.

Antarctica is known for its extreme environmental conditions. It is the best model to study multiple stress factors at a time on human physiological responses. Although the coastal Antarctica is on Sea level but the Antarctic plateau or pole at high altitude. Since Antarctica is also becoming tourist site it is pertinent to have a proper understanding of altitude induced illnesses. In this review we have described the human acclimatization process at high altitude of Antarctic polar plateu and South Pole. The review also highlighted the symptoms, clinical features and prevention of altitude induced diseases. 

A man I knew had an extreme allergy to poison ivy when he was a child. When he was about four-teen, he was hanging out with a group of his friends who dared him to eat some poison ivy. He did, and never got poison ivy again. Presumably, the ingestion of the allergen led to the development of immunity. This might be a pathway to eliminating allergies–ingest the allergen. For example, cutting up poison ivy leaves into small pieces and crushing them with a mortar and pestle should lead to some juice in the mortar. Allow that to evaporate and have a test subject ingest the resultant powder, which, like pollen, etc., could be compressed into a pill. Wait 48 hours, and then see if the subject gets a rash when a small, unimportant area of the body is exposed to poison ivy leaves–and have Ivy-Dry handy. This could be a way to eliminate allergies–ingestion of the allergen.

Molecular interactions between proteins or between proteins and small molecules are pivotal events for selective binding of biological structures and, consequentially, for their correct function. In this scenario, the evaluation of kinetic parameters, characterizing a molecular interactions, is considered a crucial event to reveal the nature of binding processes. The focus on peculiar forces involved in the molecular recognition represents an opportunity to explore biological interactions in real time, and to develop a number of innovative biotechnological methods for diagnosis and/or therapy. Currently, optical biosensors, offering an increasingly effective technology to detect in real time molecular binding, are usually composed by a detector, a sensor surface and a sample delivery system: only definite substances, which are able to interact specifically with the biological part, lead to an optical or electrical signal of the physical transducer. In this review we want to highlight the exponentially-growing interest of Surface Plasmon Resonance (SPR) based optical biosensors for molecular binding analysis in different research fields.

Background: Varicocele therapy is a controversial issue. No single approach is adopted as the best therapeutic option. Testes get blood supply from testicular artery, cremasteric artery and artery to the vas deference. So ligation of testicular artery in the abdomen do not cause ischemia to the testis. This was already demonstrated in many studies. Classical Palomo varicocelectomy also consists of open ligation of testicular vessels in the retroperitoneum. En mass ligation of testicular vein and artery is technically easy and fast in laparoscopic varicocelectomy (LV). Chance of missing some veins are also less. Henceforth recurrence is also less. Recurrence and post-operative complications are high when only testicular vein is ligated by laparoscopy in the retroperitoneum. We wanted to see the outcome of laparoscopic varicocelectomy by mass ligation technique. Methods: 56 patients of symptomatic varicoceles were included in the study from the outpatient services. Symptomatic varicoceles of grade 2 to grade 3 were operated from January 2012 till January 2019 over a period of 7(seven) years in Jahurul Islam Medical college Hospital. The patients were selected for dull pain and ugly veins not for infertility. All were operated by laparoscopy with en-mass ligation of testicular vein and artery in the retroperitoneum. They were followed up for a period of six months after surgery. We collected all the data in a retrospective manner. Results: The average operation time was 27±3 minutes. Average post-operative hospital stay was 32±7 hours. There were no technical failures requiring conversion to open varicocelectomy. There was no incidence of hydrocele formation nor testicular atrophy. One patient of bilateral varicocele had 50% reduction of his varicocele. We considered this a recurrence. All other patient had complete reduction of varicocele. One patient developed hemo-peritoneum due to dislodgement of hemo-clip, which required laparotomy. He did not require any further surgery for his varicocele. Conclusion: Laparoscopic varicocelectomy with mass ligation technique is safe, effective, less time consuming and easy to perform. Recurrence and post-operative complications are minimum. Plastic hemo-lock should be used rather than titanium heom-clip for ligation of testicular vessels. There is no incidence of testicular atrophy or any adverse effect on testis.

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]. 

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.

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].

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.
