Abstract
INTRODUCTION The spleen is one of the frequently injured solid organs in abdominal blunt trauma. The standard of care is nonoperative nowadays depending on the hemodynamic stability (World Society of Emergency Surgery (WSES) grade I-III) of the patient due to advancements in treating modalities. Operative interventions are required in hemodynamically unstable patients or failure of nonoperative management. The study was planned to find the clinical spectrum of abdominal blunt trauma, specifically those having splenic trauma, and their subsequent management in an institution. METHODS This is a retrospective observational study. All included patients with blunt abdominal injuries were treated in a level 1 trauma center between July 2021 and December 2022. Data regarding demographic profile, blood transfusion, pre- and postoperative findings, and management including the period of hospital stay, morbidity, and mortality were collected and analyzed. RESULTS One hundred sixty-four patients were analyzed, of which 142 were males and 22 were females. The commonest mechanism of injury was motor vehicle collision, followed by falls. Grade III splenic injury was the most common injury, while the predominantly associated injury was rib fracture. The patients were managed preferably through nonoperative management, followed by angioembolization and operative management. The commonest postoperative complication was pneumonia. CONCLUSIONS Nonoperative management of splenic trauma has evolved as the standard of care replacing operative management in order to sustain its immune function, thereby preventing overwhelming post-splenectomy infection.

Abstract
Psoriatic Erythroderma (PsE) is a presentation of Erythroderma due to a history of psoriasis showing inflammation and exfoliation of epidermal skin characterized by erythema and scaling. There is no definite treatment in contemporary medical science but the principle-based Ayurvedic approach has been proved to be effective. We present a case of PsE treated for 3 months with Ayurvedic herbomineral preparations and dietary restrictions for non-vegetarian and dairy items. As per the Ayurvedic diagnostic view, the presented case is correlated with Audumbara Kushtha and Ekakushtha due to their intricate features. Thus, Ayurvedic approaches were directed to eliminate vitiated doshas responsible for acute exacerbation of Kushtha (∼dermatitis) and to maintain equilibrium among them. The patient was initially considered as a case of Saam stage of Kushtha with Pitta-Rakta-Vata predominance. Thus, management was planned into different domains-treatment of Saam stage of Kushtha, Vyadhipratyanika chikitsa (∼disease antagonistic treatment), Rasayana intervention (∼Immunomodulation therapy) and Ayurvedic drugs were given accordingly. The assessment was done based on subjective parameters and PASI score. The patient was followed for about one and half year without any complication and relapse. This case study shows PsE can be managed with an Ayurvedic approach and proper diet planning.

Abstract
BACKGROUND Recent reports from this lab have demonstrated a higher incidence of NETs, nitrosative, as well as oxidative stress, and have a direct correlation with the severity of sepsis and organ damage. However, the mechanistic perspective of NETs induced organ damage has not been understood at the cellular and molecular level. Interaction of inducible nitric oxide synthase (iNOS) with Rac2 in regulating reactive oxygen species (ROS) and reactive nitrogen species (RNS) generation and its implications in microbial killing has been reported. This study was, therefore, undertaken in neutrophils of sepsis patients to investigate the functional importance of iNOS-Rac2 interaction in ROS/ RNS, peroxynitrite generation, NETs generation, and NETs mediated cell death. METHODS The study was conducted on 100 patients with sepsis and 50 healthy volunteers. Interaction between iNOS and Rac2 was performed using co-immunoprecipitation and co-immunolabeling assay. Free radicals involving ROS and RNS were evaluated using cytochrome c reduction assay. NETs formation was evaluated by fluorescence microscopy. The cytotoxic effect of NETs was assessed on lung carcinoma cell line (A549) using colorimetric Alamar blue assay. RESULTS Enhanced interaction between iNOS and Rac2 was found in sepsis neutrophils in comparison with control. This was accompanied by an increased level of superoxide (O2.-), nitric oxide (NO), and peroxynitrite (ONOO-) which were decreased in the presence of NAC, DPI, and 1400 W, signifying the role of iNOS-Rac2 interaction. Enhanced NETs release from activated sepsis neutrophils were abrogated in the presence of DPI. NETs from sepsis neutrophils exert a cytotoxic effect on lung epithelial cells (A549) in a concentration-dependent manner. CONCLUSION Our findings exhibit the functional role of iNOS-Rac2 interaction in ROS/RNS, peroxynitrite generation, NETs generation, and NETs mediated cell death.

Abstract
Raja Ramanna Centre for Advanced Technology (RRCAT) has an ongoing program to develop 650 MHz, 5-cell elliptical superconducting RF (SCRF) cavities under the Indian Institutes and Fermilab Collaboration. The elliptical multi-cell SCRF cavity fabrication process involves forming of half-cells and their precise machining and joining by electron beam welding to form end groups and dumbbells, which are then joined to make the final cavity. To ensure that the final welded cavity achieves physical lengths and resonant frequencies within design tolerance and has good field flatness, the measurement and correction of resonant frequency are carried out for dumbbells and end groups. A novel method to identify the frequency of individual half-cells in a dumbbell cavity and a dedicated tuning fixture to correct them had been developed. The paper details the RF characterization and correction procedure employed during fabrication of the first six 650 MHz cavities at RRCAT.

Abstract
COVID 19 has been declared a Public Health Emergency of International Concern by the WHO (1). The management of COVID 19 pandemic by Govt. of India has been applauded by the WHO for its timely and strict actions. No doubt we have borrowed time from the lockdown but it could have been utilized in a much better way to control. The epidemiological opinion is that the harshest lockdown was acceptable but its extension was not required as we have not been able to sustain the benefits of lockdown gained in the beginning. The gain of lockdown could have been better had it been coupled with meticulous contact tracing and containment measures during the early period of pandemic. A subsequent failure to ensure all these together resulted in spread of virus everywhere in spite of lockdown. It has also given a false feeling to the public that lockdown will prevent infection.

Abstract
Myasthenia gravis is a disease of great challenge to the anesthesiologist, because it affects the neuromuscular junction. Anesthetic management involves either muscle relaxant or non-muscle relaxant techniques. This case report documents the safe use of fentanyl, propofol and sevoflurane combination guided by bispectral index, without the use of muscle relaxants in a patient with myasthenia gravis who presented for meningioma surgery.

Abstract
The Western Ghats (WG) of India, one of the hottest biodiversity hotspots in the world, has witnessed major land-use and land-cover (LULC) change in recent times. The present research was aimed at studying the patterns of LULC change in WG during 1985-1995-2005, understanding the major drivers that caused such change, and projecting the future (2025) spatial distribution of forest using coupled logistic regression and Markov model. The International Geosphere Biosphere Program (IGBP) classification scheme was mainly followed in LULC characterization and change analysis. The single-step Markov model was used to project the forest demand. The spatial allocation of such forest demand was based on the predicted probabilities derived through logistic regression model. The R statistical package was used to set the allocation rules. The projection model was selected based on Akaike information criterion (AIC) and area under receiver operating characteristic (ROC) curve. The actual and projected areas of forest in 2005 were compared before making projection for 2025. It was observed that forest degradation has reduced from 1985-1995 to 1995-2005. The study obtained important insights about the drivers and their impacts on LULC simulations. To the best of our knowledge, this is the first attempt where projection of future state of forest in entire WG is made based on decadal LULC and socio-economic datasets at the Taluka (sub-district) level.

Abstract
OBJECTIVE To investigate the incidence of Nosocomial Infection (NI) and type of bacteriological isolates among the patients admitted in the medical and surgical wards of a non-teaching secondary care hospital in north India. MATERIALS AND METHODS This was a cross-sectional hospital based study conducted in the Wards of General Medicine, General Surgery and Orthopaedic of the hospital. The patient were admitted in the department for various surgical procedures, without evidence of initial infection, were included in the study. RESULTS A total of 176 patients were included in the study of which 82 were from Medical and 94 from Surgical ward. Overall incidence of NI was found to be 26.1% (Medical ward=28%, Surgical ward=24.5%., p=0.58). The isolation rate of Acinetobacter baumanii was (p=0.15) higher among the patients of medical ward (95.7%) than surgical ward (82.6). Escherichia coli was isolated in 89.1% and no significant difference was observed between medical and surgical wards. Klebsiella pneumoniae was isolated in 50% patients and was almost similar (p=0.37) in medical surgical wards. The isolation rate of Pseudomonos aeruginosa, Enterococcus faecalis, Staphylococcus aureus and Coagulase negative staphylococci were 43.5%, 73.9%, 34.8% and 17.4% respectively. A significant difference was observed in the isolation rate of Enterococcus faecalis (p=0.007) and Coagulase negative staphylococci (p=0.002) between medical and surgical wards. Overall, among the patients who developed NI, 27.2% patient's bacterial isolates were Gram positive (Surgical=64.1, Medical=80%). CONCLUSION The incidence of NI is increasing in the hospitals, so extensive that more care has to be taken in cleaning the wards of the hospitals.

They lead to permanent diminution of vision which can be managed by Penetrating Keratoplasty (PK). PK is removing diseased as well as healthy tissues and is associated with many post-operative complications. Deep Anterior Lamellar Keratoplasty (DALK) is a relatively newer procedure which replaces only the diseased stroma, leaving the original corneal endothelium intact. This procedure is associated with lesser incidence of post-operative complications. METHODS The study was conducted at a large tertiary care centre. 10 patients with stromal corneal scars were subjected to DALK and results were analysed after 06 months. Poor quality donor corneal tissue of B- and C grade was used in all cases. RESULTS 7 out of 10 patients (70%) undergoing DALK had post-operative visual acuity of 6/24 or better. 03 patients who did not have adequate recovery of visual acuity were due to over-riding of the graft in 01 case (10%), fungal keratitis in 01 case (10%) and interface haze in 01 case (10%). CONCLUSION DALK is a promising new technique for management of superficial corneal stromal scars using poor quality donor corneal tissue. Initial results are encouraging with minimal complications.

Abstract
Penetrating injuries of the anterior fontanelle are exceedingly uncommon and are most often associated with inflictedinjury. This report of a 7-month-old male infant, whose father was working with a knife which accidentally slipped from his hand and penetrated the infants anterior fontanelle and frontal lobe, demonstrates that accidental injuries may also occur rarely.

Abstract
OBJECTIVES To study the knowledge and practices related to newborn care in urban slums of Lucknow city, UP, and to identify critical behaviors, practices, and barriers that influence the survival of newborns. MATERIALS AND METHODS A cross-sectional study in urban slums of Lucknow city, UP, included 524 women who had a live birth during last 1 year preceding data collection. Data were analyzed using statistical software SPSS 10.0 for windows. RESULTS Study findings showed that about half of the deliveries took place at home. Majority (77.1%) of the mothers believed that baby should be bathed with warm water and dried with clean cloth and 79.7% mothers practiced it. Only 36.6% mothers initiated breast-feeding within 1 h of birth and 30.2% initiated after 1 day. The mothers who have not given colostrum to their baby, in majority the reason was customs. CONCLUSION In majority of cases, correct knowledge and correct practices regarding newborn care were lacking among mothers and this should be promoted through improved coverage with existing health services.

Abstract
Kisspeptin, as well as insulin-like growth factor-1 (IGF-1), act centrally to stimulate luteinizing hormone-releasing hormone (LHRH) secretion at puberty. IGF-1 can induce KiSS-1 gene expression as an early pubertal event; however, the signaling pathway mediating this effect is not known. Since alcohol (ALC) blocks IGF-1 induced LHRH release acutely, we assessed whether this drug could affect IGF-1 stimulated prepubertal KiSS-1 gene expression following a binge type of exposure. Immature female rats were administered either ALC (3 g/kg) or water via gastric gavage at 07.30 h. At 09.00 h the ALC and control groups were subdivided where half received either saline or IGF-1 (200 ng) into the third ventricle. A second dose of ALC (1.5, 2 and 3 g/kg) or water was administered at 11.30 h. These regimens produced moderate blood alcohol concentrations of 77, 89 and 117 mg/dl, respectively, over the time course of the experiment. Rats were sacrificed 6 h after the IGF-1 injection and tissues containing the anteroventral periventricular (AVPV) and arcuate (ARC) nuclei were collected. IGF-1 stimulated (P<0.01) KiSS-1 gene expression in the AVPV nucleus at 6 h, but did not affect expression of the kisspeptin receptor, GPR54. While ALC did not alter basal expression of either gene, its dose dependently blocked IGF-1-induced KiSS-1 gene expression in the AVPV nucleus. No changes were observed in the ARC nucleus. Assessment of IGF-1 signaling indicated that the acute administration of IGF-1, ALC, or both did not alter the basal expression of IGF-1 receptor protein. However, IGF-1 stimulated (P<0.05) phosphorylated Akt protein over basal levels, an action blocked by ALC. Our results indicate that the IGF-1 induction of KiSS-1 gene expression is mediated by Akt activation, and that ALC alters this important prepubertal action of IGF-1.

Abstract
OBJECTIVE To assess the rates, timing and causes of neonatal deaths and the burden of stillbirths in rural Uttar Pradesh, India. We discuss the implications of our findings for neonatal interventions. METHODS We used verbal autopsy interviews to investigate 1048 neonatal deaths and stillbirths. FINDINGS There were 430 stillbirths reported, comprising 41% of all deaths in the sample. Of the 618 live births, 32% deaths were on the day of birth, 50% occurred during the first 3 days of life and 71% were during the first week. The primary causes of death on the first day of life (i.e. day 0) were birth asphyxia or injury (31%) and preterm birth (26%). During days 1-6, the most frequent causes of death were preterm birth (30%) and sepsis or pneumonia (25%). Half of all deaths caused by sepsis or pneumonia occurred during the first week of life. The proportion of deaths attributed to sepsis or pneumonia increased to 45% and 36% during days 7-13 and 14-27, respectively. CONCLUSION Stillbirths and deaths on the day of birth represent a large proportion of perinatal and neonatal deaths, highlighting an urgent need to improve coverage with skilled birth attendants and to ensure access to emergency obstetric care. Health interventions to improve essential neonatal care and care-seeking behavior are also needed, particularly for preterm neonates in the early postnatal period.

Abstract
A series of 5-[(N-substituted benzylidenylimino)amino]-2-oxo/thiobarbituric acids (3a-3h) have been synthesized by the condensation of 5-hydrazino-2-oxo/thiobarbituric acids (2a-2b) with various aromatic aldehydes. Cycloaddition of thioglycolic acid to 3a-3h, yielded 5-[(2'-substituted phenyl-4'-oxothiazolidin-3'-yl)amino]-2-oxo/thiobarbituric acids (4a-4h). All these compounds were screened, in vivo, for their anticonvulsant activity and acute toxicity studies. Compounds 4f and 4g were found to be most potent compounds of this series and were compared with the reference drugs, phenytoin sodium, lamotrigine and sodium valproate. The structures of these compounds have been established by IR, 1H NMR and mass spectroscopic data.

Abstract
Dengue, an important human arboviral infection, is endemic in many parts of India. Outbreaks are now reported quite frequently from different parts of the country. We report here findings of serological investigation of serum samples received during a recent outbreak of dengue infection in Delhi from September to November 2003. Acute phase serum samples from suspected cases of dengue infection (including dengue fever, dengue haemorrhagic fever and dengue shock syndrome) of duration 5 days, were tested for dengue specific IgM antibodies by enzyme linked immuno sorbant assay (ELISA). Of the 874 serum samples tested, 456 (52.3% ) were positive for dengue specific IgM antibodies. The maximum number of positive cases was reported in October, peaking in second and third week. Patients in the age group of 21-30 yr accounted for 34.2 per cent of positive cases. This outbreak was less severe as compared to the previous 1996 outbreak and showed a shift towards an older age group.

5-[1'-[3"-Aminoacetyl-2"-methyl-6",8"-dihalosubstitutedquinazolin-4"(3"H)-onyl]-thiosemicarbazido]-2-oxo/thiobarbituric acids 3a-3h and 5-[2'-amino-5'-[3"-aminomethylene-2"-methyl-6",8"-dihalosubstitutedquinazolin-4"(3"H)-onyl]-1',3',4'-thiadiazol-2'-yl]-2-oxo/thiobarbituric acid 5a-5h were prepared by incorporating 1-[3'-aminoacetyl-2'-methyl-6",8"-dihalosubstituted-quinazolin-4'(3'H)-onyl]-thiosemicarbazides 2a-2d and 2-amino-5-[3'-aminomethylene-2'-methyl-6',8'-dihalosubstituted-quinazolin-4'(3'H)-onyl]-1,3,4-thiadiazoles 4a-4 h respectively at 5(th) position of 2-oxo/thiobarbituric acids (via Mannich reaction). All the newly synthesized compounds were screened for their anti-convulsant activity in MES and PTZ models and were compared with standard drugs phenytoin sodium and sodium valproate. Interestingly, these compounds were found to be devoid of sedative and hypnotic activities when tested. Out of the compounds studied, the most active compound 5h, that is 5-[2'-amino-5'-[3"-aminomethylene-2"-methyl-6",8"-dibromoquinazolin-4"(3"H)-onyl]-1',3',4'-thiadiazol-2'-yl]-2-thiobarbituric acid showed activity (90%) more potent than the standard drug.

Abstract
The methanolic, chloroform and ether extracts of Euphorbia tirucalli latex and stem bark were evaluated for larvicidal activity against laboratory-reared larvae of Culex quinquefasciatus (Diptera: Culicidae), vector of the brancroftian filariasis and worst urban nuisance mosquito. The latex extracts contain more potent larvicidal components (177.14 mg/L-326.37 mg/L) than the stem bark extracts (237.663 mg/L-513.39 mg/L). The order of toxicity (LC50) for the latex extracts was Methanol extract (177.14 mg/L) > Chloroform (200.76 mg/L) > Ether (326.37 mg/L) while the rank of order of toxicity (LC50) of stem bark extracts was Ether (237.66 mg/L) > Chloroform (343.515 mg/L) > Methanol (513.387 mg/L), Higher doses (LC90 24 h of mosquito larvae) of each extract did not cause any mortality among fishes after 24 h. The study gave a weight into the possibility of formulating suitable preparation from the latex and stem bark extracts of the plant for use in mosquito control programme.

Abstract
Analgesic, antipyretic and anti-inflammatory activities of newly synthesized spirobarbitunylphenothiazines viz 10-[7, 11-Di(4-4' dimethoxphenyl)-3-oxo-9-methylaminoimino-2, 4-diazaspiro [5.5] undecane 1, 5 dione] acetylphenothiazine (test drug A) and 10-[7, 11-Di (N.N-dimethylaminophenyl)-3-oxo-9-methylaminoimino-2, 4-diazaspiro [5, 5] undecane-1, 5 dione] acetylphenothiazine (test drug B) have been screened in Swiss mice and Wistar rats. The peripheral analgesic activity of test drugs A and B was investigated by acetic acid induced writhing test in Swiss mice while the central analgesic action was assessed by hot-wire (tail flick test) of the analgesiometer and tail-clip test in Wistar rats. Antipyretic activity was assessed on Brewer's yeast induced pyrexic model while antiinflammatory activity was seen on carrageenan induced hind paw oedema. Analgesic activity was found to be only of peripheral type as there was reduction of 66% in writhing responses by test drugs A and B in dose of 80 mg/kg in mice. No change in the tail flick responses was observed on analgesiometer or by tail clip by both the test drugs. Reduction of 1.5 to 2.0 degrees C in rectal temperature was observed in pyretic rats by test drugs A and B in dose of 80 mg/kg. 80% reduction in paw volume was noted in 80 mg/kg dose of both the test drugs which was comparable to the anti-inflammatory activity of 300 mg/kg, p.o. of phenylbutazone.

Abstract
During the past decade intense investigation has focused on cellular aging with the expectation of discovering factors that regulate the replication complex and contribute to the onset and progression of cellular aging. The most striking feature of cellular aging is the failure of sensing diploid cells to enter or complete S phase of the cell cycle. The G1/S phase transition is an initial critical step in the regulation of proliferation in eukaryotic cells, and significant advances have been made toward understanding the basic mechanisms of aging by identifying components of the macromolecular assemblies participating in the G1/S transition. These studies have identified multiple DNA polymerases and their accessory factors, and have provided important strategies for investigating the molecular events that contribute to aging processes. DNA replication, repair and recombination in eukaryotic cells require the action of a variety of DNA polymerases, at least six of which are known, alpha, beta, gamma, delta, epsilon, and zeta. Among them the highly conserved DNA polymerase alpha-primase (pol alpha-primase) is the only enzyme capable of initiating DNA replication at chromosomal origin sites and at sites of initiation of discontinuous synthesis of Okazaki fragments on the lagging side of the replication fork. Numerous protein factors that play strategic roles in DNA replication have been identified and the understanding of their regulation has been an important step for identifying the elements that are involved in, and possibly necessary for, governing cellular senescence and aging. In this review we summarize the current information regarding DNA pol alpha modulation during aging. We focus in particular on the coordinated actions of DNA pol alpha in the presence of other cellular proteins involved in the replication complex in the hope that understanding pol alpha interactions with components of the replication complex may provide insight into the mechanisms by which aging and age-related diseases occur.

Abstract
Our hypothesis is that leptin release is controlled neurohormonally. Conscious, male rats bearing indwelling, external, jugular catheters were injected with the test drug or 0.9% NaCl (saline), and blood samples were drawn thereafter to measure plasma leptin. Anesthesia decreased plasma leptin concentrations within 10 min to a minimum at 120 min, followed by a rebound at 360 min. Administration (i.v.) of lipopolysaccharide (LPS) increased plasma leptin to almost twice baseline by 120 min, and it remained on a plateau for 360 min, accompanied by increased adipocyte leptin mRNA. Anesthesia largely blunted the LPS-induced leptin release at 120 min. Isoproterenol (beta-adrenergic agonist) failed to alter plasma leptin but reduced LPS-induced leptin release significantly. Propranolol (beta-receptor antagonist) produced a significant increase in plasma leptin but had no effect on the response to LPS. Phentolamine (alpha-adrenergic receptor blocker) not only increased plasma leptin (P < 0.001), but also augmented the LPS-induced increase (P < 0.001). alpha-Bromoergocryptine (dopaminergic-2 receptor agonist) decreased plasma leptin (P < 0.01) and blunted the LPS-induced rise in plasma leptin release (P < 0.001). We conclude that leptin is at least in part controlled neurally because anesthesia decreased plasma leptin and blocked its response to LPS. The findings that phentolamine and propranolol increased plasma leptin concentrations suggest that leptin release is inhibited by the sympathetic nervous system mediated principally by alpha-adrenergic receptors because phentolamine, but not propranolol, augmented the response to LPS. Because alpha-bromoergocryptine decreased basal and LPS-induced leptin release, dopaminergic neurons may inhibit basal and LPS-induced leptin release by suppression of release of prolactin from the adenohypophysis.

Abstract
BACKGROUND Steroidogenic acute regulatory protein (StAR) is a 30 kDa mitochondrial protein that plays an essential role in steroid hormone biosynthesis by facilitating delivery of cholesterol across the mitochondrial membrane, where side chain cleavage occurs to initiate ovarian steroidogenesis. Because ethanol (EtOH) suppresses estradiol secretion in prepubertal female rats, we evaluated the effects of EtOH on prepubertal ovarian StAR. METHODS At 0700 hr, 28-day-old female rats were gavaged with saline or a 3 g/kg dose of EtOH. At 0800 hr, half of each of these two groups was treated with 15 IU of pregnant mare serum gonadotropin (PMSG). At 1000 hr, a 2 g/kg dose was administered to maintain moderately elevated blood alcohol levels. At 1600 hr, all of the animals were killed by decapitation, and blood and ovaries were collected for measurement of serum pregnenolone and estradiol and for ovarian StAR gene and protein expression. RESULTS Northern blot analysis showed two major transcripts of 3.8 and 1.7 kb of ovarian StAR mRNA. The ovaries from EtOH-treated rats showed decreased (p < 0.01) basal expression of both 3.8 and 1.7 kb StAR transcripts. PMSG-stimulated animals showed a more than 4-fold increase (p < 0.001) in the levels of both transcripts, when compared with ovaries from animals that received saline or EtOH only. Conversely, in EtOH-treated animals, the PMSG-stimulated expression of the 1.7 kb transcript was blocked, and the increase in the 3.8 kb StAR transcript was blunted (p < 0.05 vs. PMSG). Western blot analysis revealed that EtOH exposure also depressed (p < 0.01) the basal expression of StAR protein. PMSG-stimulated animals showed an increase (p < 0.001) in levels of StAR protein, and this was blocked (p < 0.01) by EtOH. These changes observed in ovarian StAR mRNA and protein were paralleled by changes in serum pregnenolone and estradiol. Specifically, acute EtOH exposure suppressed (p < 0.05) the basal levels of both steroids. Furthermore, PMSG-stimulated animals showed an increase in the production of pregnenolone (p < 0.05) as well as estradiol (p < 0.01), and EtOH blocked this stimulatory action of PMSG on both steroids. CONCLUSION These results demonstrate for the first time that EtOH is capable of altering ovarian StAR expression, which contributes to the detrimental effect this drug has on ovarian steroidogenesis during prepubertal development.

Abstract
Two hundred and sixty seven patients of uncomplicated P. falciparum malaria completed study in a multicentric phase III clinical trial of Arteether. Arteether was given intramuscularly in a dose of 150 mg daily for three consecutive days. Each patient was followed upto 28 days of alpha, beta arteether therapy. The cure rate was 97% with fever clearance time between 1-7 days (24-168 hours) and parasite clearance time between 1-3 days (24-72 hours). Parasite reappearance rate was found to be 3% and reported at only three of the centres. Following the treatment no adverse effect was observed on haematological, biochemical and vital clinical parameters.

Abstract
Alcohol consumption during early adolescence may suppress the secretion of specific female reproductive hormones, thereby delaying puberty and adversely affecting the maturation of the reproductive system. These effects occur through several mechanisms, including altered production and secretion by the ovaries of estradiol, a key steroid hormone involved in the timing and regulation of female reproductive events. Alcohol can affect estradiol production by interfering with the normal function of regulatory hormones produced by the brain and the pituitary gland. Recent research has demonstrated additional potential mechanisms for alcohol's effects on female reproductive capability, including interference with specific regulatory systems located entirely within the ovary. Such "intraovarian" systems include the insulin-like growth factor-1 (IGF-1) and nitric oxide (NO) systems. Alcohol can dampen the stimulatory effects of the ovarian IGF-1 system and can increase the inhibitory effects of the ovarian NO system. These effects combine to decrease estradiol secretion. Thus, alcohol impairs ovarian function not only by interfering with hormonal communication between the brain, pituitary gland, and ovaries but also by directly altering the function of regulatory systems within the ovaries themselves. These results provide further evidence of the risks of underage drinking and the importance of its prevention.

Abstract
The title compounds were prepared by reaction of beta-acetylamino-naphthalene with different aromatic aldehydes followed by cyclisation with hydrazine hydrate and with different primary or secondary amines (Mannich's reaction), respectively. The structures of new compounds were confirmed by 1H-NMR and IR spectral data. Anti-inflammatory and ulcerogenic activities in vivo were evaluated and compared with the standard drugs, phenylbutazone and indomethacin. Some compounds of the series exhibited promising anti-inflammatory activity with a lower ulcerogenic liability than the standard drugs.
