Abstract
In the context of natural resource degradation, migration can act as means of adaptation both for those leaving and those supported by remittances. Migration can also result from an inability to adapt in-situ, with people forced to move, sometimes to situations of worse or of the same exposure to environmental threats. The deleterious impacts of resource degradation have been proposed in some situations to limit the ability to move. In this contribution, we use remote sensed information coupled with population density data for continental Africa to assess quantitatively the prevalence of migration and immobility in the context of one cause of resource degradation: drought. We find that the effect of drought on mobility is amplified with the frequency at which droughts are experienced and that higher income households appear more resilient to climatic shocks and are less likely to resort to mobility as an adaptation response.

Abstract
INTRODUCTION An important aspect of the prevention of complications in percutaneous nephrolithotomy (PCNL) is to reduce the likelihood of injury to the adjacent structures and perirenal tissues. AIM To determine the efficiency and safety of renal puncture during mini-PCNL with a new atraumatic needle MG. MATERIALS AND METHODS A total of 67 patients who underwent mini-percutaneous nephrolithotomy at the Institute of Urology and Human Reproductive Health of Sechenov University were included in the prospective study. For the purpose of homogeneity of the groups, those with staghorn nephrolithiasis, nephrostomy, a history of prior kidney surgery (including PCNL), renal and collecting system anomalies, acute pyelonephritis, and blood clotting disorders were not included. The main group consisted of 34 (50.7%) patients who underwent atraumatic kidney puncture with a new needle MG (MIT, Russia), while in the control group there were 33 (49.3%) patients, who underwent standard puncture with Chiba or Troakar needles (Coloplast A/S, Denmark). The outer diameter of all needles was 18 G. RESULTS In patients with a standard access, a hemoglobin decrease in the early postoperative period was more pronounced (p=0.024). The incidence of complications according to the Clavien-Dindo classification did not differ significantly (p=0.351), however, a JJ stent was placed in two patients from the control group due to impaired urine flow and the development of urinoma. CONCLUSION Together with a similar stone-free rate, atraumatic needle allows to reduce a hemoglobin drop, as well as less development of severe complications.

Abstract
Significant amounts of feedstock metals will be required to build the infrastructure for the green energy transition. It is currently estimated, however, that the world may be facing an "infrastructure gap" that could prevent us from meeting United Nations Sustainable Development Goal targets. Prior investigations have focused on the extractive aspects of the mining industry to meet these targets and on looming bottlenecks and regional challenges in these upstream market segments. Scant attention has been paid to the downstream processing segments of the raw materials value chain, which also has a high degree of market concentration. Growing international tensions and geopolitical events have resulted in a shift toward "reshoring" and "near-shoring" of mining processing capabilities as regional powers attempt to make metal supply chains more secure. While increasing resilience, these shifts can also dilute the overall effectiveness of the global mining supply network and subsequently hamper the world's ability to close the green energy infrastructure gap. We argue that broadening the remit of the International Renewable Energy Agency (IRENA) to include coordinating these mission-critical metal processing functions can mitigate these issues. The G20 is one potential forum for enabling an integrated mineral processing agreement under the auspices of IRENA.

Abstract
Bleeding is a serious complication of percutaneous nephrolithotomy (PCNL). A rare cause of gross hematuria is a calico-venous fistula. A clinical case of successful intraoperative diagnosis and treatment of calico-venous fistula during PCNL is presented in the article. Description of a clinical case. A patient J., 53 years old, underwent examination and treatment at the Institute of Urology and Reproductive Health, FGAOU VO I.M. Sechenov First Moscow State Medical University with a diagnosis of staghorn stone of the right kidney, a stone of the left kidney, chronic right-side pyelonephritis. On June 15, 2021, mini-PCNL was performed for the staghorn stone of the right kidney. The procedure seemed to be unremarkable, but during intraoperative antegrade pyelography, the inflow of contrast agent from the lower calyxes into the posterior segmental vein of the right kidney was detected, which was managed by creating sufficient traction of the nephrostomy drainage. Communication of the collecting and venous systems of the kidney is associated with a risk of both severe gross hematuria and urine flow into the venous bed. The urine flow into the bloodstream may result in hemodynamic disturbances, up to collapse followed by cardiac arrest. In order to prevent complications of PCNL it is necessary to analyze the kidney anatomy based on three-dimensional modeling of contrast- enhanced computed tomography. A calicovenous fistula can be a source of risk of bleeding and severe complications. To minimize intraoperative damage to parenchymal structures, an analysis of three-dimensional modeling of a kidney in patients with staghorn calculus based on computed tomography is required, which allows rational planning of surgical tactics.

Abstract
INTRODUCTION surgical treatment of urinary stone disease plays an important role in urological practice. Stone fragmentation can be performed using various lithotripters, from which Holmium fiber laser (Ho: YAG) has currently taken the main place. According to the current literature, a superpulsed thulium fiber laser with a wavelength of 1.94 m and a maximum power output of 40 W showed in vitro higher efficiency compared to Ho: YAG, while having the same safety profile. The use of a thulium fiber laser with a pulse energy of 0.025-6 J and a high repetition rate (up to 1600 Hz) allows to most effectively perform stone dusting during retrograde intrarenal surgery (RIRS). AIM to improve the performance of RIRS using the 1.94m superpulsed thulium fiber laser. MATERIALS AND METHODS a total of 152 patients with renal stones who were treated during the period from February 2018 to July 2019 were included in the study. The analysis of the laser settings, their effect on retropulsion and visibility when performing RIRS using a superpulsed thulium fiber laser with a wavelength of 1.94 m and a maximum power output of 40 W, a peak power of 500 W, as well as an assessment of the stone-free rate the first postoperative day and 3 months after the procedure was done. RESULTS The most frequently used settings were as following: 0.5 J, 30 Hz, 15 W (No. 1), 0.15 J, 200 Hz, 30 W (No. 2), 0.8 J, 31.25 Hz, 25 W (No. 3), 0.8 J, 37.5 Hz, 30 W (No. 4). The statistical analysis of the influence of the settings on the quality of endoscopic imaging and retropulsion was carried out. In addition, the features of each settings were analyzed. The stone-free rate on the first postoperative day was evaluated using low-dose CT. CONCLUSION A superpulsed thulium fiber laser with a wavelength of 1.94 m and a maximum power of 500 W has shown high efficiency in clinical practice when performing RIRS, since it allows to have good endoscopic imaging, minimal retropulsion, and to perform stone dusting, which had a positive effect on the stone-free rate. Optimization of the settings of thulium fiber lithotripsy may improve the results of surgical treatment of urinary stone disease.

Abstract
Material flow has been accelerated from underground natural minerals and is accumulating as aboveground waste stock. China is not only the largest producer and consumer of material-driven products, but also the largest generator of product waste. No official annual product waste data are released for China, which creates challenges especially in light of China's emerging waste management policies. Previous studies have presented only estimations of waste streams for single products. In this study, we considered three product types and 33 technological products and collected all the available data. A Kuznets curve and Bass diffusion model were employed to forecast their future consumption. Based on urban consumption metabolism, we created one systematic estimation model of product waste generation related to material flow and social regulation. Typical technological product waste outflows were estimated from 2010 to 2050, which can assist further material flow and environmental impact research, as well as waste management policy-making and technology development. The created model can be potentially extended to other types of product waste estimation.

Abstract
Anthropogenic mineral is absorbing wide concern in the context of circular economy, but its generation mechanism and quantity from product to waste remain unclear. Here we consider three product groups, 30 products, and use the revised Weibull lifespan model to map the generation of anthropogenic mineral and 23 types of the capsulated materials by targeting their evolution from 2010 to 2050. Total weight of anthropogenic mineral on average in China reached 39 Mt in 2010, but it will double in 2022 and quadruple in 2045. Stocks of precious metals and rare earths will increase faster than most base materials. The total economic potential in yearly-generated anthropogenic mineral is anticipated to grow markedly from 100 billion US$ in 2020 to 400 billion US$ in 2050. Furthermore, anthropogenic mineral of around 20 materials will be capable to meet projected consumption of three product groups by 2050. While a large quantity of underground mineral resources can be converted into manufactured products, a majority is still solid waste disposal. Here the authors found a large increase in total weight of anthropogenic mineral from 2010 to 2050 with faster growth rate for precious metals.

Abstract
AIM to evaluate the possibilities and efficiency of using 3D technologies for the laparoscopic interventions in patients with renal and ureteric stones. MATERIALS AND METHODS A retrospective analysis of the results of surgical treatment of patients with renal and ureteric stones performed in the urology clinic of the I.M. Sechenov First Moscow State Medical University of Minzdrav of Russia for the period from January 2012 to December 2017 was carried out. During this period a total of 4958 interventions were done. Among them, 98 laparoscopic (1.97%) surgeries were performed, including nephron-sparing interventions (n=47; 48%), pyelolithotomy (n=15; 15.3%), ureterolithotomy (n=32; 32.65%) and partial nephrectomy (n=4; 4.05 %). The average patients age was 55.76+/-10.5 (29-80) years. There were 51 men (52%) and 47 women (48%). The mean stone density was 1237.6+/-354.6 HU (from 500 to 1913 HU). In 14 (22.9%) cases, nephrostomy tube or ureteric stent had been put before surgery. In addition, 40 (40.8%) patients previously underwent one surgical intervention on the kidneys and 17 patients with urinary stone disease (17.3%) underwent surgery more or equal 2 times. 88 (89.8%) patients had severe concomitant diseases and the most common pathology in 51 (52.0%) patients with urinary stone disease was arterial hypertension. In 11 (11.2%) cases, the interventions were performed in patients with abnormal kidneys, including horseshoe kidney (n=6; 6.1%), duplicated collecting system (n=3; 3.1%) and pelvic kidney (n=2; 2%). In addition to standard preoperative diagnostic methods in 22 cases (22.4%) the 3D-planning and multivariate virtual performing of intervention based on the multidetector computer tomography scan was done using Amira 3D-modeling program. Among these patients, virtual interventions were performed prior to all pyelolithotomy and partial nephrectomy. Intraoperative data of virtual constructions were used by surgeons as navigation. The interventions were performed by seven urologists at the clinic with various experience in laparoscopic surgery. RESULTS The mean duration of laparoscopic pyelolithotomy, laparoscopic partial nephrectomy, laparoscopic ureterolithotomy and laparoscopic nephrectomy was 183.2+/-69.6, 201.3+/-35.2 min, 97.6+/-43.7 and 165.4+/-92.3 min, respectively. The minimal blood loss was observed during laparoscopic ureterolithotomy (53.33+/-31.2 ml). During these interventions, in 8 cases (8.16%) a flexible endoscope was used for inspection and complete removal of stones. Intraoperative complications were noted in 6 patients (6.1%). There were 4 conversions to open surgery (4.1%). Postoperative surgical complications were observed in 1 (1%) patient, while non-surgical complications developed in 4 patients (4.1%). There was no mortality. CONCLUSION Laparoscopic access for the treatment of patients with urinary stone disease should be used for the treatment of patients with large, long-standing ureteral calculi and patients with kidney stones who have concomitant pathology of kidney or upper urinary tract (UPJ obstruction, kidney tumors) requiring surgical intervention. Laparoscopic access should be considered primarily for the planning of laparoscopic partial nephrectomy and laparoscopic nephrectomy in patients with urinary stone disease. The use of 3D computer-assisted technologies is advisable for patients with urinary stone disease and abnormal kidneys if laparoscopic pyelolithotomy, partial nephrectomy or ureterolithotomy is planned.

Abstract
In this empirically grounded perspective, we explore how, if managed correctly, mining might go beyond a straight conversion of finite natural capital to financial resources. We suggest a process where mineral extraction could act as a catalyst for more diversified growth and even serve as a basis to restore forms of 'natural capital' it had previously diminished. The case in point-small in scale but significant in consequence-is the particularly challenging instance of the small-island state of Nauru, which has a very negative history of socio-ecological impacts of phosphate mining. Yet, the degraded landscape requires capital investment which could be reaped from restoration of the land using revenues generated from exporting the waste rock pinnacles as branded household counter-tops and pavement stone products with an "island provenance premium". Furthermore, we use an industrial ecology method to show that Nauru's secondary phosphate can be shown to be less environmentally impactful than comparable phosphate from other sources. This has potential for further "green branding" of the Island's products. We contend that implementing such a restoration approach that harnesses the remaining mineral capital with care has the potential, to diversify the island's economy from one dependent on extractive industries and donors to agroforestry, fishing and tourism. A holistic approach is offered that considers prudent use of Nauru's remaining mineral resources towards an agenda of ecological restoration and economic diversification that will allow the island to prosper after the phosphates it has traditionally relied upon are depleted.

Abstract
Abstract
Background:
The dual technique with radio colloid and blue dye is the gold standard in sentinel lymph node biopsy (SLNB) to stage axilla in breast cancer. However due to cost & infrastructural demands of nuclear medicine department most of the oncology centers are not doing slnb or are doing SLNB with blue dye which is not a standard of care. Indocyanine green (ICG) has recently been used as a method of identifying sentinel lymph nodes. Studies have shown that ICG fluorescence imaging alone or in combination with the blue dye method or the radionuclide method is a safe and easy technique. The objective of the present study was to assess the diagnostic performance of sentinel lymph node (SLN) biopsy using the indocyanine green (ICG) fluorescence method compared with that using the conventional method in detection of sentinel lymph nodes.
Material & Methods:
60 patients diagnosed with early breast cancer underwent the SLNB procedure using technetium-99m radio colloid (R), methylene blue dye (MB), and ICG. Fluorescence imaging was done using an indigenously designed , very economical fluorescence imaging system, Irilic.nm fluorescence imaging along with Indocyanine green. All SLNs that were removed during surgery were labelled as hot, blue or/and fluorescent and sent for pathological examination. The detection rate of SLNs and positive SLNs, and the number of SLNs of ICG, MB+ R, ICG + MB, ICG + R were compared. Injection safety of ICG and MB was evaluated.
Results:
Sentinel Lymph Node was identified in all 60 cases. Total Sentinel lymph nodes removed was 145 (Mean=2, Range 2-5), ICG was able to identify more nodes than the dual dye technique. The identification rate with the dual dye technique was 95%, with blue dye alone 93.6% and with radioisotope alone 96.8% whereas with ICG alone was 100%, with ICG + MB was 96.6% & ICG + R was 96.6 %. 28(46.6%) out of 60 patients had positive nodes which was identified by both dual dye & ICG. None of the patients had any local or systemic reaction with ICG, 3 patients with blue dye had tattooing & staining of skin.
Conclusion:
ICG is as effective as the dual dye for SLNB. ICG is safe & reliable. In addition, as a near-infrared dye, it has the advantages of real-time visualization, lower cost, and wider availability. It can be a boon for developing countries & second tier referral centers of developed country where there is limited access to nuclear medicine department & radiocolloid and even if its accesible the cost involved is too high which comes with added radiation exposure to medical personnel handling them. A combination of blue dye and ICG is useful dual approach when radioisotope is unavailable.

Abstract
Mining poses serious and highly specific threats to biodiversity. However, mining can also be a means for financing alternative livelihood paths that, over the long-term, may prevent biodiversity loss. Complex and controversial issues associated with mining and biodiversity conservation are often simplified within a narrow frame oriented towards the negative impacts of mining at the site of extraction, rather than posed as a series of challenges for the conservation science community to embrace. Here, we synthesize core issues that, if better understood, may ensure coexistence between mining and conservation agendas. We illustrate how mining impacts biodiversity through diverse pathways and across spatial scales. We argue that traditional, site-based conservation approaches will have limited effect in preventing biodiversity loss against an increasing mining footprint, but opportunities to improve outcomes (e.g. through long-term strategic assessment and planning) do exist. While future mineral supply is uncertain, projections suggest demand will grow for many metals and shift mining operations towards more dispersed and biodiverse areas. Initiating dialogue between mining companies, policy-makers and conservation organizations is urgent, given the suite of international agendas simultaneously requiring more minerals but less biodiversity loss.

Abstract
Disturbances of vitamin D metabolism is one of the factors leading to the impairment of phosphate and calcium homeostasis which plays leading role in the development of urinary stone disease. Vitamin D is necessary for wide spectrum of physiologic processes and good health condition. Until now, in many guidelines on urolithiasis there is an advice to limit vitamin D intake due to concerns of an increase in the stone formation. In vivo studies have shown that 1,25()2D3 can both increase and decrease and not to influence on calcium excretion. The results of the studies assessing the relationship between vitamin D blood/plasma level and urinary stone disease are often inconsistent and even controversial. In patients with urinary stone disease the vitamin D deficiency is often found and currently there is still a lack of studies dedicated to problem of vitamin D deficiency in patients with urinary stone disease and the need for its correction.

Abstract
Unlike adult mammals, adult frogs regrow their optic nerve following a crush injury, making Xenopus laevis a compelling model for studying the molecular mechanisms that underlie neuronal regeneration. Using Translational Ribosome Affinity Purification (TRAP), a method to isolate ribosome-associated mRNAs from a target cell population, we have generated a transcriptional profile by RNA-Seq for retinal ganglion cells (RGC) during the period of recovery following an optic nerve injury. Based on bioinformatic analysis using the Xenopus laevis 9.1 genome assembly, our results reveal a profound shift in the composition of ribosome-associated mRNAs during the early stages of RGC regeneration. As factors involved in cell signaling are rapidly down-regulated, those involved in protein biosynthesis are up-regulated alongside key initiators of axon development. Using the new genome assembly, we were also able to analyze gene expression profiles of homeologous gene pairs arising from a whole-genome duplication in the Xenopus lineage. Here we see evidence of divergence in regulatory control among a significant proportion of pairs. Our data should provide a valuable resource for identifying genes involved in the regeneration process to target for future functional studies, in both naturally regenerative and non-regenerative vertebrates.

Abstract
PURPOSE to compare various methods of upper urinary tract drainage in patients with urolithiasis. PATIENTS AND METHODS 60 patients were included into a prospective study which ran from March 2013 through December 2014. All patients underwent PCNL with a nephrostomy tract diameter of (28-30 Ch.) at the I.M. Sechenov First Moscow State Medical University urology clinic. Patients were divided into 2 groups. Group 1 30 (patients) underwent nephrostomy after PCNL with nephrostomy tract placement, in group 2 (29 patients) internal drainage was performed. One patient withdrew from the study due to residual stone. Adequacy of urinary tract draining was assessed by operative time and blood loss. A comparative analysis was performed to outline difference in both groups by length of hospital stay, severity of flank pain in early postoperative period and 5 days after the procedure, day of drain removal. RESULTS the average operative time in group No1 was 104 minutes (+/-17 min.), and 71 minutes (+/- 19 minutes) in group No2 . The average hemoglobin level before surgery in both groups was roughly comparable and amounted to: 141.5g / l (+/-13) in group No1, in group No 2 143.6 g / l (+/-18). At the same time, hemoglobin level in the early postoperative period varied in both groups and was as follows: 121g / l (+/-13) in group No1, and 128g / l (+/-14) in group 2. Evaluation of pain severity by VAS score showed that severity of pain in an early postoperative period was roughly comparable in both groups and amounted to 6.29 and 6.05 points, respectively, but from the second day, and since the activation of the patients, the values of the intensity of pain in both groups became differ. Group No1: - 5.33 (+/-1.5) on day 2, 3.25 (+/-1.8) on day 3, - 2.5 (+/-1.6) on day 5. A more thorough elucidation of the cause of pain showed that in 56 (88%) patients the pain was due to the nephrostomy and pain in the nephrostomy stroke while driving and only 7 (11%) patients complained of a pain in the operated kidney. Group No2: - 3.5 (+/-1.2) on day 2, - 2.9 (+/-1.4) on day 3, 1.22 (+/-0.8) on day 5. CONCLUSION A detailed and thorough history, taking together with multislice computed tomography and multiplanar 3D modeling allows for better preoperative assessment regarding a size, a number and location of stones, vascular architecture of the kidney. This enebles an experienced endoscopic surgeon to plan an operation, and avoid the possible difficulties associated with lithotripsy and choose a more suitable method of pyelocaliceal system draining after the operation. In turn, tubeless PCNL, with proper intraoperative managamant and careful selection of patients appears to be safe and effective. Drainage of the upper urinary tract with internal drainage reduces intensity of postoperative pain, which improves the quality of life of patients in the postoperative period, and reduces the length of postoperative stay.

Abstract
OBJECTIVES To study the effect of Vitamin D3 supplementation on metabolic control in an obese type 2 diabetes Emirati population. METHODS This randomized double-blind clinical trial was conducted with 87 vitamin D-deficient obese, type 2 diabetic participants. The vitamin D-group (n=45) and the placebo group (n=42) were matched for gender, age, HbA1c and 25-hydroxy vitamin D (25(OH) D) at the baseline. The study was divided into two phases of 3 months each; in phase 1, the vitamin D-group received 6000 IU vitamin D3/day followed by 3000 IU vitamin D3/day in phase 2, whereas the placebo group (n=42) received matching placebo. RESULTS After supplementation, serum 25(OH) D peaked in the vitamin D-group in phase 1 (77.2±30.1 nmol/l, P=0.003) followed by a decrease in the phase 2 (61.4±18.8 nmol/l, P=0.006), although this was higher compared with baseline. In the placebo group, no difference was observed in the serum 25(OH) D levels throughout the intervention. Relative to baseline serum, parathyroid hormone decreased 24% (P=0.003) in the vitamin D-group in phase 2, but remained unchanged in the placebo group. No significant changes were observed in blood pressure, fasting blood glucose, HbA1c, C-peptide, creatinine, phosphorous, alkaline phosphatase, lipids, C-reactive protein or thyroid stimulating hormone concentrations compared with baseline in either group. CONCLUSIONS Six months of vitamin D3 supplementation to vitamin D-deficient obese type 2 diabetes patients in the UAE normalized the vitamin D status and reduced the incidence of eucalcemic parathyroid hormone elevation but showed no effect on the metabolic control.

Abstract
This study was designed to evaluate selected chemical and microbiological treatments for the conversion of certain local agro-industrial wastes (rice straw, corn stalks, sawdust, sugar beet waste and sugarcane bagasse) to ethanol. The chemical composition of these feedstocks was determined. Conversion of wastes to free sugars by acid hydrolysis varied from one treatment to another. In single-stage dilute acid hydrolysis, increasing acid concentration from 1 % (v/v) to 5 % (v/v) decreased the conversion percentage of almost all treated agro-industrial wastes. Lower conversion percentages for some treatments were obtained when increasing the residence time from 90 to 120 min. The two-stage dilute acid hydrolysis by phosphoric acid (1.0 % v/v) followed by sulphuric acid (1.0 % v/v) resulted in the highest conversion percentage (41.3 % w/w) on treated sugar beet waste. This treatment when neutralized, amended with some nutrients and inoculated with baker’s yeast, achieved the highest ethanol concentration (1.0 % v/v). Formation of furfural and hydroxymethylfurfural (HMF) were functions of type of acid hydrolysis, acid concentration, residence time and feedstock type. The highest bioconversion of 5 % wastes (37.8 % w/w) was recorded on sugar beet waste by Trichoderma viride EMCC 107. This treatment when followed by baker’s yeast fermentation, 0.41 % (v/v) ethanol and 8.2 % (v/w) conversion coefficient were obtained.

Abstract
BACKGROUND Since 1997, legislations pertaining to safe blood transfusion (SBT) have evolved considerably in Pakistan. The objective of this study was to evaluate the SBT practices in the blood banks of Pakistan. METHODS Twenty-three blood banks were randomly selected from a list of registered 40 in Karachi, the largest city in Pakistan. To evaluate the SBT practices in the selected blood banks, a questionnaire and a checklist were administered during 2007-2008. RESULTS Of the 23 blood banks surveyed, 4 (17%) were affiliated with government or a semi-government institution; 16 (70%) blood banks had a healthy donor recruitment program and 2 (9%) of the blood banks agreed that they recruited remunerated (paid) blood donors. Donors were screened for HIV, Hepatitis B, Hepatitis C and syphilis by all 23 blood banks, whereas malaria was screened by all blood banks but one. CONCLUSION SBT practices in Karachi have improved since 1995; an active role by the government in policy-making has proven effective.

Abstract
The semi-private property rights arrangement called the Household Production Responsibility System (HPRS) was started in the early 1980s in Xilingol pasture of Inner Mongolia (China), and stimulated the development of stockbreeding. The grassland has been degrading severely with increasing numbers of livestock. Based on a historical review of property rights regimes in Inner Mongolia and empirical surveys in Xilingol pasture during 2001-2003, this paper assesses the implementation of HPRS and its impacts on incomes of households as well as the environmental impact on the grassland. It was found that HPRS does not mitigate the "Tragedy of the Commons", instead it has exacerbated the situation. It was also found that co-management of grassland and livestock among a few households presents a sustainable use of grassland to develop livestock breeding. We conclude with the recommendation that small-scale collective property rights systems should be encouraged in Xilingol pasture of Inner Mongolia.

Abstract
To measure asthma prevalence and severity among children in Baghdad, we randomly sampled 3360 primary-school children and had their parents complete standardized questionnaires. The response rate was 86%, male to female ratio was 0.75:1 and age range was 6-12 years. Prevalence of wheezing ever was 25.0%. Wheezing during the last 12 months was 19.9% and 2.9% of the children had more than 12 attacks. Parents reported nocturnal wheezing for 16.3% of the children and severe attacks that limited speech for 10.5%. Prevalence of asthma ever was 22.3%. Asthma was detected in 81.9% of those with wheezing in the last 12 months. Males were predominant among children with wheezing ever, whereas females were predominant among children with asthma ever. Prevalence rates of asthma and of severe asthma symptoms decreased with increasing age.

Abstract
Substrate inhibition, which is one of the most frequently observed phenomena in the biological treatment of industrial wastewaters, has been the subject of numerous studies. Yet there are still cases which cannot be adequately described by the existing models. In this paper, a review of substrate inhibition approaches was made. A new model is proposed that assumes a common mechanism for substrate and product inhibition. The model is a continuous function having a maximum growth rate at the critical substrate concentration, beyond which the growth rate decreases as the substrate concentration is increased. The model also predicts the maximum substrate concentration where the growth ceases. The model was tested using existing data in the literature to assess the model response and predictability of critical points. The literature datahave been selected from the studies conducted on pure and mixed cultures in batch and continuous reactors for phenol and several phenolics as well as from the studies which employed the Haldane model. A curve fitting method was used to determine the model parameters. The fit of the model to the data was satisfactory, particularly for the substrate concentrations exceeding maximum growth rate.

Abstract
We previously found that the stable overexpression of oestrogen receptor-alpha in the human endothelial cell line ECV304* inhibits its growth in vitro, and that this inhibition is possibly mediated through a down-regulation of the vasoactive agents endothelin-1 and vascular endothelial growth factor. Here we show an in vivo growth-inhibitory effect of oestrogen receptor-alpha overexpression in tumours initiated in nude mice from the same clone of ECV304. In addition, we show that this growth inhibition is accompanied by an alphavbeta3-mediated inhibition of cell migration in vitro, and a down-regulation of the integrin alphavbeta3, vascular endothelial growth factor and vascularization in vivo. The levels of vascular endothelial growth factor and integrin alphavbeta3, through their effect on cell growth and migration, contribute to the process of angiogenesis and to the pathogenesis of atherosclerosis and cancer. The results shown here demonstrate that a higher level of oestrogen receptor-alpha in the cell, through its effect on certain angiogenic factors, may play a role in the control of angiogenesis.

Abstract
SV40 large T antigen (TAg) is a powerful oncoprotein capable of transforming a variety of cell types. The transforming activity of TAg is due in large part to its perturbation of the retinoblastoma (pRB) and p53 tumor suppressor proteins. In addition, TAg binds to several other cellular factors, including the transcriptional co-activators p300 and CBP, which may contribute to its transformation function. Several other features of TAg that appear to contribute to its full transformation potential are yet to be completely understood. Study of TAg therefore continues to provide new insights into the mechanism of cellular transformation.

Abstract
A high level of estrogen receptor-alpha (ER-alpha) is believed to be favorable in the prognosis and treatment of certain female cancers. ER-alpha expression in the ER-negative breast cancer cell lines inhibits their proliferation and invasive, metastatic potential in vitro. We stably overexpressed the ER-alpha in the human endometrial cancer cell line Ishikawa and showed that, unlike estradiol, high levels of ER-alpha significantly inhibit the growth of tumors xenografted from the Ishikawa cells. Subsequent to ER-alpha overexpression, in vivo down-regulation of vascular endothelial growth factor was observed in tumor xenografts. In addition, these tumors showed an inhibition of vascularization and of the angiogenic agent, integrin alphavbeta3. Involvement of a switch in the angiogenic pathways during tumorigenesis has been a recent focus of interest. Our results indicate that a high level of ER-alpha may be beneficial in the control of female cancers because of its inhibitory effect on such angiogenic pathways.

Abstract
Studies with mammalian vascular cells have suggested growth inhibitory effects of estrogen on the vascular wall. To investigate the involvement of estrogen receptor-alpha (ER) in the control of endothelial cell proliferation, we have stably transfected human estrogen receptor-alpha cDNA into the endothelial cell line ECV304. The clone ECV-ER, thus obtained, over-expresses estrogen receptor to a level approximately 10-fold higher than the parent cell line. Effects of this over-expression were studied on the cell growth rate, and on the levels of secreted endothelin-1 and vascular endothelial growth factor (VEGF). Similar to the previously reported data in other cell types, we found the transfection of ER in ECV304 cells to be inhibitory to their growth. Our ER-over-expressing clone of ECV304 also showed an inhibition of secreted endothelin-1 and VEGF levels. Moreover, the growth inhibition of this ER-over-expressing clone was reversed by the addition of endothelin-1 or VEGF to the medium. In view of the growth-stimulatory effect of endothelin-1 and VEGF on vascular cells, our results indicate that estrogen receptor-alpha may bring about its growth inhibition partly by suppressing endothelin-1 and/or VEGF production in ECV304 cells.

Abstract
Efforts have been done to recover proteins from waste liquors rich in protein in a soluble form. Cheese whey and animal bloods are by-products from the manufacture of cheese and meat. It contains a variety of proteins which can be reclaimed. The efficiency of protein precipitation from the sweet-cheese whey by the use of hydroxyethyl cellulose (HEC) was similar to that precipitated by the use of carboxymethyl cellulose (CMC). Both are greater than that precipitated by trichloro acetic acid. The same results of the efficiency of precipitation were attained when the plasma was precipitated. It was found that cheese-whey protein-HEC-complex and plasma protein-HEC-complex contain a large amount of essential amino acids. Electrophoretic separation of whey protein complex showed that beta-Lactoglobulin forms the major fraction while in case of plasma protein complex albumin forms the major fraction. The fractionation patterns of different complexes with HEC, CMC or TCA gave the same components and about the same ratio. It appears from these results that HEC-protein complexes are preferable than CMC-protein complexes or proteins precipitated by TCA. Chemical analysis of whey protein complexes revealed that lactose content of whey protein-HEC-complex was higher than that of CMC-complex or protein precipitated by TCA. Elemental analysis of protein complexes showed that the level of sodium, phosphorus, and potassium was increased while that of copper or zinc decreased. Cellulose derivative protein complexes showed no significant effects on the liver or kidney function of albino rat and these results indicted that no toxic effect was observed from the uses of these protein complexes in feeding.

Abstract
We compared the effects of evening administration of sustained-release theophylline (Uniphyl) and qid inhaled beta 2-agonist (salbutamol, two 100-micrograms puffs) on sleep quality and nocturnal oxygen saturation in 20 patients with COPD. Patients with FEV1 less than 70% predicted and FEV1/FVC ratio less than 70% were eligible to participate in this double-blind, crossover study, with 2-week treatment arms. Patients recorded morning and evening peak flow and symptoms in a daily diary. On the last day of each treatment period, overnight polysomnography was done. Spirometric indexes were measured before retiring and on awakening. Patients spent less time at less than 90% oxygen saturation (51 +/- 92 min vs 72 +/- 105 min; p = 0.03) during theophylline treatments than during salbutamol treatment. There was a smaller overnight decrease in FEV1 (0.04 L vs 0.13 L; p = 0.04) after theophylline than after sallbutamol treatment. FEV1/FVC ratio and maximum expiratory flow at 50% of vital capacity (V50) increased overnight with theophylline and decreased with salbutamol (p = 0.014, 0.025). Morning peak expiratory flow rate was higher with theophylline (4.0 +/- 1.7 L/s) than with salbutamol (3.6 +/- 1.8 L/s; p = 0.004). The duration of patient-reported nocturnal wheezing was lower with theophylline than with salbutamol (p = 0.006). There were no differences between treatments in sleep quantity, efficiency, staging, or subjective quality. We conclude that, compared with salbutamol, evening administration of once-daily theophylline results in better nocturnal oxygen saturation and an improvement in the overnight change in pulmonary function, without affecting sleep architecture, in patients with COPD.
