ENVIRONMENTAL LEVELS AND DISTRIBUTION OF CARBON MONOXIDE IN BUCHAREST URBAN AREA CASE STUDY: 1. 07. 2006 – 31.03.2007

Ambient concentrations of carbon monoxide in the vicinity of or inside urban and industrial areas can substantially exceed environmental background levels and can be detrimental to human health and welfare. In this period of analysis (July 2006 – March 2007), the maximum allowable concentration (MAC) was exceeded especially at Mihai Bravu and Cercul Militar. The accompanying diagrams showing the time evolution and charts revealing the spatial distribution of CO ambient air concentrations (based on GIS techniques) can be useful instruments in identifying the potential risk areas, like the important streets in the center of Bucharest

PEDOLOGICAL, PHYSICAL AND CHEMICAL DEFINITIONS OF THE RESPECTIVE SOIL STRATA WHICH COULD BE ENCOUNTERED ALONG A SLOPE WITHIN THE VINEYARD OF DEALUL OLT - DRĂGĂȘANI UPON WHICH THE VINE KIND OF TĂMÂIOASĂ ROMÂNEASCĂ HAS BEEN PLANTED

Within the Drăgășani oenological realm could be encountered a multitude of soil types and this is the reason why these ought to be precisely identified and delimited so that should a new vine plantation be founded in there the most appropriate engraft-bearing vine kind could be eventually chosen.  Our scientific research investigation has thus identified its most appropriate experimental site upon a slope endowed with a slant degree of 10% and at the surface of which a plantation of the TămâioasăRomânească vine kind has been established. Three types of soil had been therefore identified along this above mentioned slope: Pseudo-rendsinian proto-soil of anthropic origin (within the slope’s upside third part); Argillaceous brown illuvial slightly pseudo-glazed (within the slope’s middle third part); Type-casted brown eumeso-basic (within the slope’s downside third part). The purpose of the present work is thus the one of outlining the respectively pedological, physical and chemical features of these above mentioned soil types

Conservative surgery of breast cancer in women; psychological benefits

Breast surgery was one of the most dynamic fields of medicine which benefited from significant progress during the last decades. The transition from aggressive and mutilating amputations to conservative, oncoplastic and reconstructive techniques has been constant, offering improved and rewarding results, viewed from both, oncological and aesthetical perspectives. Conservative techniques, especially those which preserve the nipple areola complex, are followed by improved patient’s perception of their body image, confidence and sexuality, with the only drawback of increased anxiety linked to recurrence risk

Nerve compression due to benign tumors or ganglion cysts in the upper limb – case series

Tumor nerve compressions in the upper limb are relatively rare, usually involving ganglion cysts and benign tumors. We present a case series of five patients with peripheral nerve compression in the upper limb due to tumor or cystic masses- ulnar nerve compression in the Guyon’s tunnel due to a ganglion cyst, large median nerve schwannoma compressing anterior interosseous nerve and median nerve, voluminous lipoma compressing median nerve in the proximal forearm, superficial branch of radial nerve compression by a synovial cyst and elbow region lipoma compressing radial nerve. In the beginning, those benign lesions are asymptomatic but, as they continue to grow adjacent to a peripheral nerve clinical manifestations appear progressively as compressive neuropathies. After a preoperative imagistic analysis, tumor resection with careful dissection, in order to preserve the neurovascular structures, is the elective surgical procedure in order to obtain an optimal functional recovery

Harvesting spontaneous vegetation or purchase medicinal plants from the market? – case study

The paper analyses the effciency of material resources supplying of an enterprise that processes medicinal herbs. The objectives of the research are to identify the most cost-effective alternative of supplying herbs, out of two possible sources: spontaneous vegetation, by initiating a campaign of collection, or purchase them from contractors. Econometric models are developed for choosing the optimal solution, entering data from a business of processing medicinal herbs in a computer program. The results show that there is a quantity of material resources for which is more proftable to get it by initiating a campaign of collecting plants from spontaneous flora, after which, for any additional quantity, it becomes more effcient to be purchased from the market

THE ROLE OF VITAMIN D IN FETAL DEVELOPMENT AND IN THE OCCURRENCE OF GESTATIONAL DIABETES

Introduction. Due to the alarming global growth of metabolic disorders and the complications of these disorders, in recent years researchers have tried to find new mechanisms for b the imbalances and during their attempts have found that vitamin D, a vitamin that was not enough studied before, plays an important role in preventing metabolic disorders in pregnancy. Numerous studies have highlighted the beneficial role of vitamin D, especially in the first trimester of pregnancy. Vitamin D is a secosteroid hormone with a role in foasfo-calcic metabolism and is essential in the development of musculo - skeletal system and in the absorption of calcium. In order to become a biological active substance, after being secreted at skin, vitamin D suffers a number of metabolic processes of activation at the renal level. The latest studies have shown that in addition to the kidneys, the granulated tissue and the placenta are organs in which this hormone is activated. In addition to the effects such as immunomodulation, inhibition of keratinocyte and fibroblast proliferation, increased contractility myocardial, increased insulin production, inhibition of angiogenesis and apoptosis induction, new research has shown that vitamin D has an important role in intrauterine fetal development and in the development of gestational diabetes. Conclusions. The current medical studies reveal that vitamin D is a hormone which has an active biological action beneficial to both bone metabolism and carbohydrate metabolism. The deficit of this vitamin may increase the risk of developing gestational diabetes and intrauterine growth restriction. Since research concerning this topic is still at the beginning, subsequent studies will have to elucidate the optimum value of vitamin D in maternal serum during pregnancy, especially in the first trimester, in order to lower the risk of developing metabolic damage and intrauterine fetal restriction

WAYS TO COMPLETE PREGNANCY IN DIABETIC PREGNANT WOMEN

Introduction. Gestational diabetes is the type of diabetes characterized by the presence of glucose intolerance, that first appears or is first diagnosed during pregnancy. The diagnosis of this condition is established between the 24 th and the 28 th week of pregnancy by the presence of a single abnormal blood glucose level during the oral glucose tolerance test (OGTT). Given the complex pathology of this disease, making the right decision at the right time is the key to success for both the mother and the fetus, thus choosing the moment and way of birth in diabetic pregnancies is a challenge for the obstetrician. Material and method. Multiple studies conducted worldwide have not yet been able to determine the optimal time and manner of birth to avoid the complications that occur in pregnant women with gestational diabetes. In recent years, researchers have been looking for a perinatal care in order to find the best way to finish the pregnancy and limit the effects of gestational diabetes to both the mother and the newborn. Conclusions. The time and the way of birth for diabetic pregnancy depends on several factors, including gestational age, fetal status, pregnancy, parity, metabolic status and other pregnancy-related pathologies, technical possibilities of the hospital and professional experience of the medical team. Choosing the moment and the way of birth is a decision that must be taken individually in each case as the results of research have not yet found an optimal standard to solve this problem
