Authored by Andrea Beccarini
This letter provides an analytical solution for the covariance matrix related to the (mean) parameters of the standard Markov-switching model. The importance of avoiding numerical procedures to estimate this matrix is also highlighted. Simulations are also performed in order to verify, in small samples, the actual advantage of the analytical formula. The seminal paper of Hamilton  provides a very attractive way to estimate regime-switching parameters of a model where the latent variable governing the regime switching enters the model without its lags. In this case, closed form solutions for these estimates are available. Surprisingly, Hamilton and the subsequent applied and theoretical literature do not consider a closed form solution for the related covariance matrix. Thus, the covariance matrix is generally found by numerical procedures whose aim is generally to estimate both the point Markov- switching (M-S) estimates and their covariance matrix in the maximum likelihood (ML) framework.

Modern Materials in Surgical Correction of Genital Prolapse
Authored by Ishchenko Anton Anatolievich
Genital prolapse is a disease manifested by the displacement of the uterus and the vaginal walls to the genital slit and/or by going beyond it. At the basis of this pathology lies the dysfunctionalityof the ligament apparatus of the internal genital organs and the muscles of the pelvic floor. The causes of this pathology include physical, genetic, age, hormonal factors. Pelvic prolapse is a very urgent problem, due to the high incidence in bothpatientof thereproductive age and postmenopausal women, as well as the projected increase in morbidity in countries with excessive fertility and in countries with a high life expectancy. The most preferred method of treatment is surgical correction, based on neo-fasciogenesis with the use of gridimplants. In this study, 37 operations were performed using a titanium implant, wherethe patients were divided into three groups[1-4].

Medicine's "Future": Pilot Data from a US Sample Shows Surgeons More Likely to Encourage Children to Pursue Medicine
Authored by Irene Dimitriadis
A survey was conducted to ascertain knowledge on when doctors start having children and the likelihood of them encouraging their children to follow in their footsteps. Across all training levels, surgical specialties are more likely to encourage their children to become physicians compared to non-surgical specialties (64.3% vs 45.5%; p<0.0001, respectively). Amongst physicians with sons and daughters, 21.2% of responders report a gender bias in regards to encouraging their children to become doctors, of which almost twice as many parents report that they would encourage their son compared to their daughter to pursue medicine (14% vs 7.2%, p=0.08).

The Metaphor of Cultural Entanglement in Northeast African Archaeology
Authored by Julia Budka
Archaeology in Northeast Africa has long been dominated by ancient Egypt and its rich cultural heritage. The monuments located in modern Sudan, ancient Nubia, were first described and analyzed by Egyptologists and traditionally viewed from an "Egyptian" perspective, resulting in several shortcomings in assessing African indigenous cultures. Many studies exhibit an Egypt centric bias and are referring primarily to written Egyptian sources which have been read as accurate evidence, partly neglecting archaeological findings.

The article examines the issues of studying the world experience and the results of many years of experiments in various countries on the applicability of low-intensity irrigation systems in various climatic and soil conditions shows that the creation of irrigation systems of this type is an effective and economically viable irrigation of various types of crops: perennial plantings, orchards, vineyards, forest plantations, shrub farms as soil protection means, grain-legumes, vegetables, ridge crops and technical crops, ornamental plantations, goons, nurseries and others. The low-intensity system (drip irrigation, micro sprinkling, aerosol irrigation, subsoil and inektsionnoy irrigation, etc. which has almost universal application, in particular, it is applicable where the use of other methods irrigation is impossible or ineffective.

Fluid Shear Stress Inhibits Differentiation of Growth Plate Chondrocytes, Partially Via Integrin Beta 1
Authored by Barbara D Boyan
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.
