Mechanical stimuli such as fluid shear stress contribute to cartilage homeostasis and serve as important parameters for tissue engineering bioreactors. While mechanical forces on articular chondrocytes are widely investigated, the objective of this study was to determine the effects of fluid shear stress on growth plate cartilage cells. Rat costochondral resting zone chondrocytes (RC) and chondrogenic ATDC5 cells were subjected to 0, 2, 3.5, 5, or 6.5 dynes/cm2 fluid shear stress in a cone-plate viscometer device for 24 hours, and thenwereharvested immediately or after an additional static culture period. Shear stress exposure decreased [35S]-sulfate and [3H]-thymidine incorporation, but these were partially or fully recovered to control levels following a 24-hour, post-shear static culture across shear treatments. Alkaline phosphatase activity was also dose-dependently lowered by shear at this interval.

Corn Yield as Altered by Using On-Farm Seed Priming, Different Nitrogen Levels and Soil Moisture Regimes
Authored by Kamil Sardar
The experiment was conducted at New Developmental Farm, of The University of Agriculture Peshawar during summer 2013 to study the effect of seed priming, nitrogen (N) levels and soil moisture regimes on the yield and yield components of maize. Two separate experiments were conducted in RCB design, one under high moisture condition other under low moisture condition. Treatment combination of seed priming and N levels were kept in. Sub plots while moisture in main plots. Nitrogen was applied at (0, 75, 150kg N ha-1) in three split doses. Seed priming was consisted of dry seed, water soaked and seed primed in 0.2% Phosphorus (P) solution. Days to emergence and Emergence m-2 of maize were significantly affected by moisture and seed priming while N effect was not significant. Low moisture plots resulted in higher days to emergence as compared to high moisture plots. Higher days to emergence were recorded for dry seed as compared to P primed seed and water soaked seed.

A Case Report and Review of the Literature
Authored by Rosario Fernandez Salmerón
Dermatomyositis (DM) is a rare paraneoplasic neurological syndrome (PNS) that may precedes the development of malignancies. It´s an uncommon inflammatory myophaty with characteristic cutaneous manifestations. The association between DM and cancer has long been recognized but is becoming more clearly delineated. Several studies have documented an increased rate of malignant disease associated with DM over that observed in the general population. The incidence of ovarian cancer developing in the setting of DM was reported to be as high as 13.3 % in one series.

Mesenchymal Stem Cells Markers
Authored by Vasiliki E Kalodimou
In the field of regenerative medicine, basic research and preclinical studies have been conducted to overcome clinical shortcomings with the use of stem cells, mesenchymal stem cells and adipose stem cells. They are present in adult tissues, including bone marrow, umbilical cord, umbilical cord blood and adipose tissue . For many years, bone marrow-derived stem cells were the primary source of stem cells for tissue engineering applications. Russian-born Alexander A. Maximow in 1924 used extensive histological findings to identify a kind of spherical precursor cell in the mesenchyme, which can grow and differentiate into Different cell types. In late 1960’s the scientists Ernest A. McCulloch and James E. Till reveal for the first time the clonal nature of bone marrow cells.

Nongenomic Effect of T3 on the Na, K-ATPase Activity of Syncytiotrophoblast from Human Term Placenta
Authored by Fulgencio Proverbio
Several ion transport enzymes are positively regulated by genomic mechanisms, through the thyroid hormones T and T. However, there is evidence indicating that these hormones might also exert non genomic effects on different transporting enzymes. A normal activity of the Na, K-ATPase of syncytiotrophoblast is essential for ion homeostasis in this tissue, as well as for the growth and development of the fetus. In the current work it was studied the non genomic effect of thyroid hormones on the Na, K-ATPase activity of syncytiotrophoblast. The study was carried-out by incubating human term placental explants in the absence and presence of 10nMTor 350nMT and then isolating the syncytiotrophoblast plasma membranes and assaying them for Na, K-ATPase activity. The enzyme activity was also assayed for freshly prepared plasma membranes in the presence of (0-15)nMT or (0-500)nMT.
Changing Attitudes towards Assisted Reproduction and IVF
Authored by Kelly Oliver
If not so long ago pregnancy was something to be hidden, a private matter that required modesty in dress and behavior, now with sexy pregnant bodies and protruding baby bumps on the covers of tabloids every week, a new stigma is attached to Assisted Reproductive Technologies (ART), In Vitro Fertilization (IVF) and what goes on at fertility clinics, which is often showed in secrets. If a few decades ago a woman's pregnant body was considered obscene insofar as it was associated with sex—it was proof that she had sex--today the disconnect between sex and pregnancy made possible by new reproductive technologies appears as the new obscenity.
Semenoma Originated from an Ectopic Testis
Authored by Otheman Fahs
The authors report an observation of a meta static seminoma on an ectopic testicle in a 23 years old patient and discuss the epidemiological, diagnostic, therapeutic and evolutionary aspects of this entity. Clinical diagnosis is often difficult due to the diversity of clinical symptoms, the use of imaging, biological markers and percutaneous biopsyis essential to make the diagnosis. The anatomopathology and therapeutic aspects are similar to the testis in normal situations. Early diagnosis of these tumors involves the lowering of the cryptorchid testicles, because even if this lowering does not prevent the setumors, it allows better monitoring.

Be Wary of Using Poisson Regression to Estimate Risk and Relative Risk
Authored By Leigh Blizzard
Fitting a log binomial model to binary outcome data makes it possible to estimate risk and relative risk for follow-up data, and prevalence and prevalence ratios for cross-sectional data. However, the fitting algorithm may fail to converge when the maximum likelihood solution is on the boundary of the allowable parameter space. Some authorities recommend switching to Poisson regression with robust standard errors to approximate the coefficients of the log binomial model in those circumstances. This solves the problem of non-convergence, but results in errors in the coefficient estimates that may be substantial particularly when the maximum fitted value is large. The paradox is that the circumstances in which the modified Poisson approach is needed to overcome estimation problems are the same circumstances when the error in using it is greatest. We recommend that practitioners should be wary of using modified Poisson regression to approximate risk and relative risk.
Confidence Intervals for the Relative Risk
Authored by Michail Tsagris
Confidence interval for the ratio of two independent binomial proportions is an important measure, especially in medicine. The relative risk is such an example where accurate interval estimation is crucial. In this work we compare 4 different methods for the construction of such intervals. Simulation studies using many combinations of the sample sizes and of the true proportions reveal interesting conclusions as to the suitability of either method.
Relationship of Gelatynase B Enzyme Activity and Coronary Artery Disease
Authored by Aysegul Bayramoglu
Matrix metalloproteinases (MMPs) play an important role in the pathogenesis of atherosclerosis, the pathology underlying the majority of coronary artery disease (CAD). We planned to investigate the association of enzyme activities of gelatinase B (or matrix metalloproteinase-9) in CAD patients. For this reason,102 patients with CAD and 99 control group recruited in this study. Serum gelatinase B enzyme level determinated from these peripheral blood samples by using Enzyme-Linked Immunosorbent Assay (ELISA). The results were evaluated by using statistical analyses. The level of gelatinase B increased in patients according to control group. As a result of our study, serum gelatinase B level was associated with CAD and could be used as a clinical marker.

The uniqueness of handwriting is based on the discriminating elements of writing which are the clear manifestations of writing habits. These writing habits are greatly influenced and shaped by the culture and environment of a writer as handwriting is an acquired skill and environment is the matrix from which this art is acquired and cultivated . The development of handwriting is complex which in part is culture dependent, and culture differs with locales and undergoes constant changes. Handwriting is a fine motor skill and teachings of the motor preliminaries (such as regularity and neatness, the introduction of cultural biases such as slant, counter clockwise rotations, left to right transport, posture and grasp) of writing varies from culture to culture. It can also be defined as a culture-bound activity, where many aspects of a language are greatly influenced by the culture of an individual. Writing is a potent and conventional system of symbols, marks and signs that encodes the utterances of a language. Cultural differences in verbal expression lead to distinctive pattern of native languages. Cheng et al.  investigated the impact of native language writing system on English handwriting and found the uniqueness in English handwriting characteristics peculiar to the ethnic origin of the writers.
There are different types of small firearms including the revolver which is a rifled handgun having a revolving cylinder with chamber for loading cartridges. Revolvers of different calibers are available varying from 3mm to about 15 mm. These small firearms are usually used by police personnel/civilians for self-defense or the defense of others; and military personnel during combat. Considering the revolver's various advantages, such firearms are clandestinely manufactured by skilled gunsmith in various locations in India and smuggled out of the country by weapons traffickers for sale and global distribution. As such, gun control has become difficult. Out of total gun-violence cases received in the laboratory for last ten years, it is seen, 2% of the total (1635 number) cases are contributed by improvised revolvers. Such indigenous firearms are meticulously designed to fire different factory made ammunition.

Sudden Unexpected Death from Extraventricular Neurocytoma. A Case Report and Review of the Literature by Antigony Mitselou in JFSCI - Juniper Publishers
Central neurocytomas (CNs) are benign tumors which usually arise from the lateral ventricles [1,2]. Extra ventricular neurocytomas (EVNs) refer to tumors with similar or identical biological and histopathological characteristics to CNs, but which arise from extra ventricular parenchymal tissue . EVNs may occur at any age, but are usually seen in the third decade of life without sex preference . Presenting symptoms obviously vary depending on the location of the tumor . Histo pathologically, EVNs display a wide spectrum in morphology, such as the growth of monotonous neurocytes either in sheets, clusters, ribbons or rosettes, and neuropils dispersed in broad zones and contain a greater number of ganglion or ganglioid cells and astrocytes than CNs . Furthermore, EVNs are often misdiagnosed as oligodendrogliomas, oligoastrocytomas or oligodendroglial tumors with neurocytic differentiation . Immuno histo chemically, synaptophysin expression is positive and has been recognized as the most reliable diagnostic marker for identifying neuronal differentiation in brain neoplasia , and may thus play a vital role in the diagnosis of EVN tumors. Below we describe a rare case of sudden and unexpected death due to a clinically undiagnosed extra ventricular neurocytoma located on the midbrain.

The Opioid Epidemic - A Generation in Crisis by Oliver Morgan in Global Journal of Addiction & Rehabilitation Medicine - Juniper Publishers
On March 29, 2017 President Donald Trump tapped Governor Chris Christie of New Jersey to lead a commission fighting the opioid addiction crisis. Not a bad choice, as political appointments go. Christie’s heartfelt words about addiction went viral in 2015 during the presidential campaign and won him praise. In his last year as governor, Christie has pursued enlightened policies to help stem the tide of opioid and other drug addiction in New Jersey. He has signed legislation limiting first-time narcotic prescriptions to five days’ worth of opioids, and requiring health insurers to cover at least a minimum of six months of substance abuse treatment.
