Sustained isometric contractions of skeletal muscles produce intramuscular pressures that leads to blood flow restriction. In result an active muscle feels deficit of oxygen what bring to muscle fatigue. In another side during exercise we have physiological contradiction between raising of oxygen demand by working muscle and restriction of blood flow due to vessel pressing. To clarify this issue many research has been performed based mainly on measurement of blood flow in muscle tissue. The purpose of this study was to assess real-time changes in muscle oxygenation during a sustained isometric contractions of dorsiflexor muscle of low (30%), moderate (60%) and submaximal (90%) intensity. Experiments were conducted using the subject’s dominant (right) leg. Volunteers was recruited from eight male students of USIPC (age: 19±2 years, weight: 75±6 kg). Tissue oxygenation index (StO2) were recorded from the tibialis anterior using NIRS device (NONIN). Saturation was higher at 30% compared with both 60% and 90% MVC at all time points after start exercise and higher at 60% than 90%. Oxygen consumption (VO2) permanently increased from slow (30%) to moderate (60%) and submaximal contractions. After cessation of the each contraction there was a large and immediate hyperemic response. Rate of StO2 increasing after effort cessation what reflects the resaturation of hemoglobin which depend on integrity and functionality of vascular system and reflects blood vessel vasodilation. StO2 restoration rate permanently increased from slow (30%) to moderate (60%) and submaximal contractions too. At last on final stage of experiment arterial occlusion test has been performed to determine the minimal oxygen saturation value in the dorsiflexors. Oxygen saturation reached a 24±1.77% what is significantly higher than StO2 after 60 and 90%MVC. So, we can conclude that oxygen saturation at 60% and 90% MVC are similar and sharply decreased after start of exercise. It means that after 60% MVC take place occlusion of blood vessels due to intramuscular pressure. Oxygen consumption of active muscle increased depend on intensity of exertion according to increasing of oxygen demand. StO2 resaturation rate (Re) permanently increased from slow (30%) to moderate (60%) and to submaximal contractions. Re increasing after effort cessation reflects the resaturation of hemoglobin which depend on integrity and functionality of vascular system and reflects blood vessel vasodilation.

Pulmonary edema is a rare but potentially life-threatening iatrogenic complication after treatment through therapeutic thoracentesis of a collapsed lung due to a hydro- or pneumo-thorax. We present a case of a 25-years male, without any pathological antecedents, who went to our emergency services with dyspnoea, tachypnea, and hypoxemia. The final diagnosis made after a clinical examination and chest X-ray showed a complete collapse of the right lung due to spontaneous pneumothorax [1-3] (Figure 1).

Benzene (B), toluene (T), ethylbenzene (E) and xylene (X), collectively named as BTEX are mono-aromatic ring compounds with a 6-carbon benzene ring. Due to the presence of the aromatic ring, these compounds, especially benzene, are generally considered to be non-reactive species [1]. 

A case study of a non-COPD (Chronic Obstructive Pulmonary Disease) patient with congenital kyphoscoliosis to see the effect of pulmonary rehabilitation after 36 sessions given for chest disease in Kuwait with signs and symptoms, physical capacity, functional level, and Quality of life.

Rothmund-Thomson syndrome is a rare autosomal recessive disorder characterized by poikiloderma (skin atrophy, telangiectasia, hyper- and hypopigmentation), congenital skeletal abnormalities, short stature, premature aging, and increased risk of malignant disease. Two siblings with Rothmund-Thomson Syndrome showed the following characteristic features: severe growth failure, dystrophic nails, absent eyelashes/eyebrows, small hands, clinodactyly, microdontia and congential poikiloderma. In addition, delayed sexual development with cryptorchidism in the male and Hashimato thyroiditis in the female patient were detected. These cases are presented here because of these endocrine patterns, with the aim of drawing attention to the invisible aspects of Rothmund-Thomson syndrome.

Aims: Implication of modified N-methyl-D-aspartate receptors (NMDAR) in synaptic plasticity and learning was investigated in normal and pathological conditions. Study design: We studied the efficiency of synaptic plasticity, the development of the long-term potentiation/depression (LTP/LTD) in olfactory cortex slices, treated with antisense or sense oligodeoxynucleotides (aODNs and sODNs) to the GluN1 subunit of NMDAR. Main outcome: aODNs induced the LTD development in slices after high-frequency tetanization. Contrariwise, in sliced treated with sODNs the enhanced LTP developed. Under conditions of severe anoxia (10 min), treatment of slices with aODNs and sODNs contributed to the preservation of synaptic activity which has been blocked in the control untreated slices. In practical implications such directed up- and down regulation of NMDAR might be useful in the readjustment of brain activity by the controlling balance of excitation/inhibition.

The use of unlicensed and off-label medicines in children is widespread and has raised an increasing concern over the last years. The majority of medicines taken by children are extemporaneously compounded by pharmacist, and there is a lack of information regarding bioavailability, suitability and stability. These formulations must be prepared from pure active substance and not from commercially available dosage forms. The development of paediatric formulations, particularly those suitable for very young children, can be a challenge to pharmacists. There is limited knowledge available about the acceptability of different dosage forms, administration volume, dosage form size, taste, safety of formulation excipients regarding to age and development status. The selection of formulation and route of administration depends on the disease being treated and the clinical condition. European Guidelines and reflection papers recommend that pharmaceutical development should consider some parameters like capability, acute or long-term illness, caregiver convenience, disability, culture differences and formulations more attractive to children must be explored.

The novel coronavirus 2019-nCoV has become a bane to mankind and spread worldwide and infected many people. Thus, there is an urgent need of a cure for the severe pneumonia disease caused by this virus. In this study, In silico comparative analysis has been done for HIV protease inhibitors on coronavirus 3CLpro protein which has shown the major interactions and common amino acid residues involved in interactions. The amino acid interaction analysis has revealed two amino acids ARG4, LYS5 to be the major amino acids targets among selected ligands. The binding energy analysis has also revealed Cobicistat as one of these best suited ligand for 3CLpro.

The actions exerted by waves on a coastal structure very much depend upon hydrodynamic processes that originate on shallow waters; even though significant progresses have been made in the last few years towards a full understanding of wave breaking, design work is still largely based on classical stability formulas. The recent availability of reliable models based on the numerical integration of full Navier-Stokes equations provides an important tool, but the evaluation of forces on vertical structures in shallow waters is still a particularly delicate application because of the complex hydrodynamic issues involved. The paper presents deals with the numerical simulation of wave effects on front of a vertical obstacle on a sloping bottom, with the objective of clarifying some physical issues which are relevant towards the applicability of numerical Navier-Stokes simulation as a design tool.

The study aimed to investigate the threats to the biodiversity of ethnomedicinal plants and to find consensus information on conservation and management practices of ethnomedicinal plants to contribute sustainable utilization of ethnomedicinal plants in Kore district, Southeastern Ethiopia. The result of the survey revealed that sixty-one medicinal plants were reported by the informants from the study area. These plants are distributed in 59 genera and 37 families. Family Lamiaceae and Asteraceae were represented by 5 (8.2%) species for each family and this is the highest number of species and followed by 4 (6.5%) species of Solanaceae and Fabaceae for each family. Preference ranking analysis shows that Eucalyptus globulus scored 47, indicating that it is the most used plant for firewood in the community, followed by Olea europaea (45) and the least used plant for firewood is Juniperus procera scored 36. Paired comparison analysis showed that Olea Europeae ranked first followed by Podocarpus falcatus for the use of charcoal production in the study area. The major purposes of plant species in the study area were construction, Charcoal, Firewood, Furniture, and Fences as well as for medicinal uses. Based on direct matrix ranking analysis Juniperus procera, Eucalyptus globulus, Podocarpus falactus, Olea europaea, Hagenia abyssinica, Croton macrostachyus, and Cordia africana were the most preferred medicinal plants by local people in the study area. The analysis's findings indicated that anthropogenic influences are endangering medicinal plants. In this study area, only about 13% of medicinal plants are collected from home gardens. This shows that the effort made by the community to conserve medicinal plants is not satisfactory. Therefore, encouraging NGOs and Government offices to participate in the conservation of medicinal plants to encourage the local people to plant indigenous trees for domestic use is necessary.
