Abstract
Introduction Post-traumatic stress disorder (PTSD) is a consequence of living in today's stressful society. Patients have difficulty forgetting traumatic events. lead pollution has many effects on the nervous system, one of which is memory and learning disorders. The herbal medicine Eugenol has a beneficial effect on memory. Aim This study aims to investigate the protective effect of Eugenol on lead-induced memory impairments in stressed rats. Methods In the first experiment, the animals were divided into three groups: SPS+Saline, SPS+Pb, and naïve. The SPS+Saline, SPS+Pb groups received normal saline and lead through gavage for 21 days, while the sham group remained untreated. Rats were subjected to the modified single prolonged stress model. Memory tests were conducted one week later, evaluating freezing levels in three consecutive tests over three days. In the second experiment, rats were divided into a SPS+Pb+Saline and three treatment groups. The SPS+Pb+Saline group received daily saline injections, while the other groups received different doses of Eugenol (25, 50, and 100 mg/kg). Memory tests similar to the first experiment were conducted. Results The results showed significantly higher immobility levels in the SPS+Saline and SPS+Pb groups compared to the sham. Additionally, the SPS+Pb group had a significant higher immobility compared to the SPS+Saline group. In the second experiment, the SPS+Pb+EU 25 group showed a significant lower freezing compared to the SPS+Pb+Saline group. Additionally, freezing in the SPS+Pb+EU 50 and SPS+Pb+EU 100 groups was significantly higher than in the SPS+Pb+EU 25 group. The SPS+Pb+EU 50 group showed a significant higher freezing compared to the SPS+Pb+Saline group. Conclusion lead acetate exacerbated memory impairments in stressed rats and Eugenol, particularly at a dose of 25 mg/kg, improved these impairments. Therefore, Eugenol has the potential to partially reduce the negative effects of lead on memory in individuals with PTSD.

Abstract
INTRODUCTION Empagliflozin plays a beneficial role in individuals with type 2 diabetes at high risk of cardiovascular complications. This study aimed to assess the prevalence of individuals with type 2 diabetes who required empagliflozin based on clinical guidelines between the years 2022 and 2023. MATERIAL AND METHODS This study was a descriptive-analytical cross-sectional study conducted on a target population of patients with type 2 diabetes. Patient data, including demographic characteristics, smoking status, hypertension, hyperlipidemia, renal insufficiency, retinopathy, and proteinuria, were collected. The indication for prescribing empagliflozin was determined based on the risk of cardiovascular complications. RESULTS A total of 398 individuals with type 2 diabetes with a mean age of 58.4 years were examined. Overall, 87.4% of the patients had an indication for empagliflozin prescription. The indication for empagliflozin prescription was significantly higher in men, individuals with hyperlipidemia, those over 55 years of age, obese individuals, and smokers. The mean age, body mass index, and triglyceride levels were higher in candidates for empagliflozin prescription. Male candidates for empagliflozin had significantly higher rates of smoking and systolic blood pressure compared to females. CONCLUSIONS The findings of this study demonstrated that a significant percentage of individuals with type 2 diabetes had an indication for empagliflozin prescription based on clinical and laboratory criteria.

Abstract
Background and Aims Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a worldwide pandemic, activates signaling cascades and leads to innate immune responses and secretion of multiple chemokines and cytokines. Long noncoding RNAs (lncRNAs) have a crucial role in inflammatory pathways. Through our search on the PubMed database, we discovered that existing research has primarily focused on examining the regulatory impacts of five lncRNAs in the context of viral infections. However, their role in regulating other conditions, including SARS-CoV-2, has not been explored. Therefore, this study aimed to investigate the expression pattern of lncRNAs in the peripheral blood mononuclear cells (PBMC) and their potential roles in SARS-CoV-2 infection. Potentially significant competing endogenous RNA (ceRNA) networks of these five lncRNAs were found using online in-silico techniques. Methods Ethylenediaminetetraacetic acid (EDTA) blood samples of the control group consisted of 45 healthy people, and a total of 53 COVID-19-infected patients in case group, with a written informed consent, was collected. PBMCs were extracted, and then, the RNA extraction and complementary DNA (cDNA) synthesis was performed. The expression of five lncRNAs (lnc ISR, lnc ATV, lnc PAAN, lnc SG20, and lnc HEAL) was assessed by real-time PCR. In order to evaluate the biomarker roles of genes, receiver operating characteristic (ROC) curve was drawn. Results Twenty-four (53.3%) and 29 (54.7%) of healthy and COVID-19-infected participants were male, respectively. The most prevalent symptoms were as follows: cough, general weakness, contusion, headache, and sore throat. The results showed that three lncRNAs, including lnc ISR, lnc ATV, and lnc HEAL, were expressed dramatically higher in the case group compared to healthy controls. According to ROC curve analysis, lnc ATV has a higher AUC and is a better biomarker to differentiate COVID-19 patients from the healthy controls. Then, using bioinformatics methods, the ceRNA network of these lncRNAs enabled the identification of mRNAs and miRNAs with crucial functions in COVID-19. Conclusion The considerable higher expression of ISR, ATV, and HEAL lncRNAs and the significant area under curve (AUC) in ROC curve demonstrate that these RNAs probably have a potential role in controlling the host innate immune responses and regulate the viral replication of SARS-CoV-2. However, these assumptions need further in vitro and in vivo investigations to be confirmed.

Abstract
BACKGROUND AND AIM Early-life stressful situations and binge drinking have been thus far acknowledged as two burdensome conditions that potentially give rise to negative outcomes and then synergistically affect brain development. In this context, the hippocampus, with the greatest number of glucocorticoid receptors (GCRs) in the brain, is responsible for regulating negative responses to stress. Prolonged glucocorticoid (GC) exposure can accordingly cause oxidative stress (OS), leading to cognitive and emotional dysfunction. Against this background, melatonin, as a powerful antioxidant and hypothalamus-pituitary-adrenal (HPA) axis regulator, was administered in this study to ameliorate cognitive impairments induced by perinatal ethanol and stress exposure in adolescent male rat progeny. METHODS Wistar rat dams were exposed to ethanol (4 g/kg) and melatonin (10 mg/kg) from gestational day (GD) 6 to postnatal day (PND) 14 and then limited nesting material (LNS) from PND0 to PND14 individually or in combination. Maternal behavior was then investigated in mothers. Afterward, the plasma corticosterone (CORT) concentration, the OS marker, the corticotropin-releasing hormone receptor type 1 (CRHR1) expression, and the GCR and brain-derived neurotrophic factor (BDNF) levels were measured in the male pups. Moreover, behavioral tasks, including the elevated plus maze (EPM), the Morris water maze (MWM), the novel object recognition (NORT), and the object-location memory (OLM) tests were completed and assessed. RESULTS The quantity and quality of maternal care significantly decreased in the mothers with dual exposure to ethanol and stress. The plasma CORT concentration in the progeny also dropped in the Ethanol + LNS group, but the risk-taking behavior elevated significantly. The ethanol and stress exposure further revealed a significant fall in the GCR and CRHR1 expression levels, compared with stress alone. The results of learning and memory tasks also indicated a significant reduction in spatial learning and memory among animals exposed to ethanol and stress. The BDNF mRNA levels correspondingly increased in the Ethanol + LNS group, compared with LNS alone. In the presence of ethanol and stress, the superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities correspondingly declined. On the other hand, the malondialdehyde (MDA) levels augmented in the hippocampus of the animals with ethanol and LNS dual exposure, as compared with the control group. Melatonin treatment (MT) thus improved nursing behaviors in dams, prevented OS, enhanced the CRHR1 and GCR expression, and reduced the BDNF levels to the similar ones in the control group. The animals in the Ethanol + LNS + MT group ultimately showed an ameliorated performance at behavioral tasks, including the memory and risk-taking behavior. CONCLUSION It was concluded that MT could prevent stress response and memory impairments arising from dual exposure to ethanol and stress by inhibiting OS.

Abstract
BACKGROUND AND AIM Anxiety often occurs both concurrently and sequentially in childhood and adolescence in association with prenatal stress, which may reduce the quality of maternal care and then cause mood disorders among children in later life. Against this background, melatonin, as a powerful antioxidant, was used in the present study to ameliorate risk-taking behaviour induced by pure maternal care in rat pups. MATERIALS AND METHODS The Wistar rat dams recruited in this study were exposed to restraint stress from gestational day (GD) 11 until delivery. They further received melatonin (10 mg/kg) during the postnatal days (PNDs) 0-7 by intraperitoneal (IP) injections at 4:00 PM. The pregnant rats were then divided into four groups, namely, control, stress, stress + melatonin and melatonin, and their maternal behaviour and corticosterone levels were measured. In the offspring, the outcomes of some behavioural tasks, including the elevated plus-maze (EPM) and open-field (OF) tests were ultimately assessed. RESULTS The study results revealed that the quantity and quality of maternal care significantly declined and the plasma corticosterone levels compounded in the stressed dams. Melatonin treatment, however, improved their nursing behaviour and reduced their plasma corticosterone levels. The offspring performance in two tasks also showed an upward trend in risk-taking behaviour in the stress group, and melatonin administration ameliorated the effects of stress and lessened their anxiety-like behaviour. CONCLUSION It was concluded that prenatal restraint stress could impair stress responses and quality of maternal care, whereas postnatal melatonin administration potentially contributed to the normalization of stress reaction and anxiolysis.

Abstract
Both prenatal ethanol and early-life stress have been shown to induce reduced risk-taking and explorative behavior as well as cognitive dysfunction in the offspring. In this study, we examined the effect of combined exposure to ethanol and early stress on maternal care, exploratory behavior, memory performances, and oxidative stress in male offspring. Pregnant rats were exposed to ethanol (4 g/kg) from gestational day (GD) 6-to postnatal day (PND) 14 and limited nesting material (LNS) from PND0-PND14 individually or in combination. Maternal behavior was evaluated during diurnal cycle. The level of corticosterone hormone and markers of oxidative stress were evaluated in the pups. Risk-taking and explorative behavior were assessed with the elevated-plus maze (EPM) test and cognitive behavior with the Morris water maze (MWM), novel object recognition (NORT), and object location memory (OLM) tests. In the mothers, perinatal alcohol or LNS either alone or in combination decreased maternal behavior. In the offspring, the combination of the two factors significantly increased the pup's plasma corticosterone concentration in comparison with ethanol and LNS alone. Reduced risk-taking behavior was observed in the ethanol, LNS and ethanol + LNS groups compared with the control group, and this was amplified in the co-exposure of ethanol and LNS groups. The MWM, NORT, and OLM tests revealed spatial and recognition memory impairment in the ethanol and LNS groups. This impairment was more profound in the co-exposure of ethanol and LNS. Also, we observed a significant decrease in superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities and an increase in malondialdehyde (MDA) level in the hippocampus of ethanol and LNS co-exposed animals as compared with individual exposure of ethanol and LNS. While each factor independently produced similar outcomes, the results indicate that the dual exposure paradigm could significantly strengthen the outcomes.

Abstract
A cross-sectional study was conducted from April to June 2016 to determine the inhibitory effect of Lactobacillus strains isolated from buffalo milk and yogurt in Bandar-e Gaz, Golestan province, North-West Iran. The raw milk and yogurt samples were collected and cultivated on MRS medium by anaerobical incubation at 37 °C for 48 h. The suspected colonies were identified on the basis of Gram’s staining and conventional biochemical tests. The antibacterial activity of the cell-free supernatant extracted from Lactobacillus strains was determined using the agar well diffusion method against standard strains Escherichia coli ATCC 11303, Staphylococcus aureus ATCC 29213, Bacillus cereus ATCC 19115, Listeria monocytogenes ATCC 19111, E. coli and S. aureus isolates from local cheese samples. A total of 10 Lactobacillus spp. were isolated and identified as L. plantarum, L. casei, L. acidophilus. L. plantarum A1 and L. acidophilus R1 exhibited relatively strong inhibitory effect against S. aureus and B. cereus, respectively. Both isolates had no inhibitory effect against L. monocytogenes. L. casei B1 showed moderate inhibitory effects against L. monocytogenes. This study showed that Lactobacilli from buffalo dairy products had good inhibitory activity towards Gram-positive indicator organisms and were one of the best choices to control these pathogens in food products.

Abstract
We aimed to evaluate the effects of feeding super-conditioned corn at different temperatures on intake, growth performance, total-tract starch digestibility, rumen fermentation, blood metabolites, and feeding behavior of dairy calves. Thirty-six Holstein female dairy calves (40 ± 1.72 kg of body weight, ± SD) were randomly assigned to 1 of the following 3 treatments: (1) ground corn (control; CON; n = 12), (2) corn super-conditioned at 75°C (T-75; n = 12), and (3) corn super-conditioned at 95°C (T-95; n = 12). Three mash starter feeds with an identical nutritional composition were blended with 5% chopped alfalfa hay and fed to individually-housed calves from d 3 to 77 of their birth. All calves were fed 4 L/d of pasteurized whole milk twice daily since d 3 to 56, followed by 2 L/d of morning feeding from d 57 to 63 of age. Calves were weaned on d 63 and remained in the study until d 77. The T-75 and T-95 diets increased total-tract starch digestibility compared with the CON diet. Dry matter intake and weaning or final BW were not affected by treatments; however, average daily gain and feed efficiency increased in calves fed T-95 in the overall period. The T-95 diet increased withers height and tended to increase hip height compared with other diets, but feeding behavior did not change throughout the experimental period. Ruminal pH decreased in calves fed the T-95 diet compared with T-75 and CON diets. The molar proportion of ruminal propionate increased, whereas the acetate-to-propionate ratio tended to decrease in calves fed the T-95 compared with CON diet. Calves fed the T-95 diet had the highest blood glucose concentration, whereas a trend for increased insulin concentration was observed in calves fed T-95 compared with other diets. In conclusion, super-conditioning temperature of corn (T-95 vs. T-75 and CON) improved the average daily gain, feed efficiency, and skeletal growth, but did not influence dry matter intake during the first 77 d of age. Finally, the total-tract starch digestibility increased, whereas ruminal pH dropped during the postweaning period as super-conditioning temperature elevated.

Abstract
Early-life stress involved in the programming of stress-related illnesses can have a toxic influence on the functioning of the nigrostriatal motor system during aging. We examined the effects of perinatal stress (PRS) on the neurochemical, electrophysiological, histological, neuroimaging, and behavioral correlates of striatal motor function in adult (4 months of age) and old (21 months of age) male rats. Adult PRS offspring rats showed reduced dopamine (DA) release in the striatum associated with reductions in tyrosine hydroxylase-positive (TH+) cells and DA transporter (DAT) levels, with no loss of striatal dopaminergic terminals as assessed by positron emission tomography analysis with fluorine-18-l-dihydroxyphenylalanine. Striatal levels of DA and its metabolites were increased in PRS rats. In contrast, D2 DA receptor signaling was reduced and A2A adenosine receptor signaling was increased in the striatum of adult PRS rats. This indicated enhanced activity of the indirect pathway of the basal ganglia motor circuit. Adult PRS rats also showed poorer performance in the grip strength test and motor learning tasks. The aged PRS rats also showed a persistent reduction in striatal DA release and defective motor skills in the pasta matrix and ladder rung walking tests. In addition, the old rats showed large increases in the levels of SNAP-25 and synaptophysin, which are synaptic vesicle-related proteins in the striatum, and in the PRS group only, reductions in Syntaxin-1 and Rab3a protein levels were observed. Our findings indicated that the age-dependent threshold for motor dysfunction was lowered in PRS rats. This area of research is underdeveloped, and our study suggests that early-life stress can contribute to an increased understanding of how aging diseases are programmed in early-life.

Abstract
Fetal alcohol spectrum disorder (FASD), which is caused by prenatal alcohol exposure, can result in cell death in specific brain regions. Alcohol-induced neurocognitive defects offspring's are included with activation of oxidative-inflammatory cascade followed with wide apoptotic neurodegeneration in many brain's regions such as hippocampus. According to the latest studies, H2S (hydrogen sulfide) can protect neuronal cells via antioxidant, anti-inflammatory, and anti-apoptotic mechanisms in different animal models. Therefore, we aimed to evaluate the protective effects of H2S on ethanol-induced neuroinflammation and neuronal apoptosis in pup hippocampus with postnatal alcohol exposure. Administration of ethanol (5.27 g/kg) in milk solution (27.8 mL/kg) for each rat pups was performed through intragastric intubation on 2 to 10 postnatal days and NaHS as H2S donor (1 mg/kg) was injected on similar time, subcutaneously. For examining the antioxidant and anti-inflammatory effects, ELISA assay was performed to determine the levels of TNF-α, IL1β, and antioxidant enzymes. Immunohistochemical staining was performed to evaluate the expression levels of GFAP and caspase-3 also Nissl staining was done for necrotic cell death evaluation. H2S treatment could significantly increase the activity of total superoxide dismutase, catalase, and glutathione (P < 0.05). It also decreased the levels of TNF-α, IL1β, and malondialdehyde, compared with the ethanol group (P < 0.05). Moreover, the number of hippocampal caspase-3, GFAP-positive cells, and necrotic cells death reduced in the H2S group (P < 0.01). Based on the findings, H2S can inhibit apoptotic signaling that is mediated by the oxidative-inflammatory cascade following ethanol exposure of rat pups on postnatal period.

Abstract
According to experimental and clinical findings, fetal brain development may be interrupted by maternal alcohol consumption during pregnancy. Adult hippocampal neurogenesis is thought to play a role in cognition function (i.e. learning and memory). Recent evidence suggests that ethanol administration causes major apoptotic neurodegeneration in many regions of the rats' developing brain during the synaptogenesis period. Based on the recent studies, H2S improve learning and memory via increased neurogenesis and antiapoptotic mechanisms in different animal models. In this study, we aimed to evaluate the protective effects of hydrogen sulfide on alcohol-induced memory impairment, hippocampus neurogenesis and neuronal apoptosis in rat pups with postnatal ethanol exposure. Administration of ethanol to male rat pups was performed through intragastric intubation on postnatal days 2-10. The pups were administered 1 mg/kg of NaHS (H2S donor) on postnatal days 2-10. For examining the spatial memory, Morris water maze test was carried out 36 days after birth. Following the behavioral test, immunohistochemical staining was performed to evaluate the expression levels of BrdU, BDNF and Apoptotic cell death was detected by TUNEL staining. Hydrogen sulfide (H2S) treatment could significantly improve spatial memory impairment (P < 0.05) and significantly increase the expression of BrdU and BDNF in dentate gyrus area (P < 0.05). It also decreased positive TUNEL cells, compared with the ethanol group (P < 0.01). Based on the findings, H2S makes significant neuroprotective effects on Ethanol neurotoxicity due to its neurogenesis and anti-apoptotic activity.

Abstract
OBJECTIVES If screening to find effective drugs is possible, the inhibition of proliferation using existing drugs can be a practical strategy to control the drug resistance of cancer. Development of a system-oriented strategy to find effective drugs was the main aim of this research. MATERIALS AND METHODS An algorithm (transcriptional regulated flux balance analysis [TRFBA]) integrating a generic human metabolic model with transcriptomic data was used to identify genes affecting the growth of drug-resistant cancer cells. Drugs that inhibit activation of the target genes were found and their effect on the proliferation was experimentally evaluated. RESULTS Experimental assessments demonstrated that TRFBA improves the prediction of cancer cell growth in comparison with previous algorithms. The algorithm was then used to propose the system-oriented strategy to search drugs effective in limiting the growth rate of the cisplatin-resistant A2780 epithelial ovarian cancer cell. Experimental evaluations resulted in the selection of azathioprine, terbinafine, hydralazine and sodium valproate that appropriately inhibit the proliferation of resistant cancer cells while minimally affecting normal cells. Furthermore, experimental data indicate that the selected drugs are synergistic and can be used in combination therapies. CONCLUSIONS The proposed strategy was successful to identify drugs effective on the viability of resistant cancer cells. This strategy can enhance the potency of treatments for drug-resistant cancer cells and provides the possibility of using existing drugs.

Abstract
Cosmetic tattooing has become a risk factor for several adverse reactions related to inks, procedures, and associated clinical conditions. Development of a sarcoid reaction to the inserted tattoo pigment in the skin is not common. We report a 45 year-old patient with history of dyspnea and mild cough since two years who had subsequently developed reddish, scaly lesions in her 15-year old tattoo done near her right eyebrow. Skin biopsy of the tattoo lesion revealed cutaneous sarcoidosis which led to further investigations and a diagnosis of pulmonary sarcoidosis. The present case highlights the fact that cutaneous sarcoidosis can develop in a long-standing tattoo. Also such a patient should be screened for systemic sarcoidosis disease.

Abstract
Chronic alcoholism leads to elevated plasma and brain homocysteine (Hcy) levels, as demonstrated by animal experiments. This study was designed to evaluate the alterations in offspring rat cerebellum following increase of plasma Hcy level induced by maternal exposure to ethanol and to investigate the possible protective role of melatonin administration upon cerebellar ethanol-induced neurotoxicity. The adult female rats were divided randomly into 4 groups, including one control and three experimental groups, after vaginal plagues. Group I received normal saline, group II received ethanol (4 g/kg), group III received ethanol+melatonin (10mg/kg) and group IV received melatonin on day 6 of gestation until weaning. 21 days after birth, plasma Hcy level, level of lipid peroxidation, the activities of several antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and levels of bcl-2 and bax mRNA expression in cerebellum were determined. Our results demonstrated that ethanol could induce lipid peroxidation, and decrease antioxidants activities and increase plasma total Hcy level. We also observed that ethanol impaired performance on the rotarod and locomotor activities of rats. However, treatment with melatonin significantly attenuated motoric impairment, the lipid peroxidation process and restored the levels of antioxidant activities and significantly reduced plasma total Hcy levels. Moreover, melatonin reduced bax/bcl-2 ratio in the presence of ethanol. We conclude that these results provide evidence that ethanol neurotoxicity in part is related to increase of plasma Hcy levels and melatonin with reducing of plasma Hcy level has neuroprotective effects against ethanol toxicity in cerebellum.

Abstract
The cellular response to Leishmania major (L. major) was evaluated in vivo by delayed-type hypersensitivity (DTH) skin test reaction using leishmanin as antigen. Our previous study had shown the development of species-specific DTH reaction in sensitized guinea pigs by application of a single purified antigen from promastigotes and filtered culture supernatants of L. major. This study has shown that purified antigen is common in both stages of the life cycle and filtered culture supernatant of L. major. The common antigen was purified and analyzed from soluble Leishmania antigen (SLA) of amastigotes, promastigotes, and filtered culture supernatant of L. major by specific monoclonal antibody coupled to sepharose-4B. The purified antigen, which gave a single band of 56 kDa on sodium dodecyl sulfate polyacrylamide gel (SDS-PAGE) electrophoresis, elicited DTH response in guinea pigs sensitized with L. major. It was almost of the same degree as that produced by whole SLA. These results show that DTH inducer antigen is present in both stages of the life cycle and filtered culture supernatant of L. major.

Abstract
The potential roles of specific antibodies of different immunoglobulin G (IgG) subclasses and IgE in serological diagnosis of cystic echinococcosis (CE) were investigated by an enzyme linked immunosorbent assay (ELISA) based on Antigen 5 (Ag5). Presence of IgG1 was demonstrated in all sera from 58 patients with CE. The most discriminatory and specific antibodies found in this study belonged to IgG4 and IgE. Only one false-positive reaction was observed with IgG4 and no IgE cross-reactivity occurred with 40 sera from healthy controls. In 36 sera from patients infected with parasites other than CE two false-positive reactions with IgG4 were observed but none occurred with IgE. In immunoblotting, it was shown that IgG1 subclass was responsible for cross-reactivity of human antibodies that reacted with a 38 kDa subunit of Ag5. IgG4 and IgE antibodies could not recognize the 38 kDa subunit and under non-reducing conditions reacted with the 57 kDa subunit without any cross-reactivity to other parasites. The results demonstrated that IgG4 and IgE are the most important antibodies for serological diagnosis of hydatid cyst in an Ag5 based immunoassay system.

Abstract
The cellular response to Leishmania major (L. major) is usually evaluated in vivo by the delayed-type-hypersensitivity (DTH) test using leishmanin. Leishmanin can give false-positive reactions in areas where there is a background of leishmaniasis. In a previous study, it was shown that a 56 kDa antigen purified from promastigote and culture supernatant of L. major induce strong DTH reactions in sensitized guinea pigs. In this study, the species-specificity of this antigen was further investigated. Three groups of guinea pigs were sensitized with L. major, L. tropica, and L. infantum and both flanks of sensitized animal were injected intradermally with purified 56 kDa antigen or soluble leishmania antigen (SLA). The extent of indurations were measured after 24, 48, and 72 h. In animals which were sensitized with three species of leishmania, only those immunized with L. major showed skin reactions to purified antigen by an increase in skin thickness. Since complex antigen mixtures such as SLA and leishmanin show cross-reactivity and can be non-specific, the result obtained here suggest that 56 kDa antigen may be a useful diagnostic tool for species specific diagnosis in field studies of leishmaniasis.

Abstract
A series of hybridomas was produced by fusion of SP2/0 myeloma cells with spleen cells of mice immunized with Leishmania major (L. major). The reactivity of secreted monoclonal antibodies (mAbs) was evaluated against available leishmanin antigen by enzyme linked immunosorbent assay. Only one hybridoma designated as 7F9 secreted IgG1 mAb which was shown to be reactive with leishmanin. This mAb was further tested against four species of Leishmania (L. donovani, L. tropica, L. infantum, L. major) and a recombinant gp63. Among the four species tested it was shown to be only reactive with promastigotes of L. major. The antigen recognized by this mAb was purified and analyzed from both sonicated and supernatant cultures of L. major by immunoaffinity chromatography and reverse phase high performance liquid chromatography. The purified antigen, which gave a single band of 56kDa on sodium dodecyl sulfate polyacrylamide gel electrophoresis elicited a strong delayed-type hypersensitivity (DTH) reaction in guinea pigs sensitized with L. major. It was almost of the same degree as that produced by leishmanin. These results suggest that an L. major-specific antigen is an alternative as a specific diagnostic skin test reagent, which could lead to a better understanding of the mechanism of DTH in L. major.

Abstract
In this report we have analysed the peripheral blood lymphocyte of several patients with chronic hepatitis B virus infection with flow cytometry. Based on the presence and absence of the HBeAb, patients were divided into two groups. In both, all the patients were HBsAg positive with normal range of serum alanine aminotranferase (23.9 +/- 17.8). We have found that the immunophenotypic profiles of patients were different from healthy donors with significant decrease in CD(3)(+) T cells, specially CD(8)(+) T cells and a significant increase in the CD(19)(+) B cells. The differences were seen in other subset of T cells (CD(4)(+)) or NK cells (CD(56)(+)/CD(16)(+)) and HLA-DR markers were not significant. When the phenotypic profiles of both groups were compared with each other, such changes were more dominant in group II, with HBeAb positive than in group I, with HBeAb negative. Also, we have seen a correlation between the increase of CD(19)(+) B cells and the decrease of CD CD(3)(+) T cells. No such correlation was observed with other cells.

Abstract
The present study completed a previous randomized trial that demonstrated the protective effect of 1-year psoas training on lumbar bone loss in postmenopausal women. Computerized tomography had been carried out at the beginning (CT1) and at the end (CT2) of this trial. In the present study, 67 women having completed the first trial were asked to practice psoas exercises (60 hip flexions in sitting position with a 5 kg weight on the knee) for 2 additional years with a third CT control at the end of this period (CT3). The aim of this complementary study was to assess the compliance rate and long-term effect on bone of daily psoas muscle training over a longer period. Twenty-one women performed this daily psoas training for 3 years from CT1 to CT3, and 14 acted as controls during the same period. Fourteen women were controls during the first year (from CT1 to CT2) but practiced psoas training during the following 2 years (from CT2 to CT3). Four women were psoas trained during the first year (from CT1 to CT2) and subsequently crossed over to the control group for the last 2 years. The compliance rate was 42%, with an attendance rate of 88%. The lumbar bone loss was lower in the 21 women trained over the 3 years (-3.26 +/- 28.45 mg/cm3) than in the 14 untrained women (-16.79 +/- 8.51 mg/cm3) (P = 0.02). The bone loss was not significantly reduced between the two periods of the study in the 12 women having been controls from CT1 to CT2 and having crossed over to the active training group from CT2 to CT3. Psoas training may be effective against lumbar bone loss. We conclude that specific training may play a contributing role in the preventive strategy to avoid osteoporosis.

A substantial accumulation of hydroxyphospholipids, to levels 3-5 times control values, followed exposure to two or more TPA treatments (24-72 h intervals), whereas single applications were ineffective. Sodium borohydride reduction increased the yield of product by approximately 50%, suggesting the additional presence of phospholipid hydroperoxides in the oxidized lipids. Straight phase HPLC analysis of the constituent hydroxy fatty acids, followed by gas chromatography/mass spectrometry, revealed that oxidized derivatives of linoleic acid, including 9- and 13-hydroxyoctadecadienoic acids (9- and 13-HODE), were the primary products. Stereochemical analysis showed ratios of S to R stereoisomers of 1.3 for 13-HODE and 1.27 for 9-HODE, which implied that TPA-induced peroxidation was primarily due to free radical oxidation, although a partial contribution of enzyme (lipoxygenase) activity is possible. The TPA-induced peroxidation was greater in the epidermis than in the dermis. Pre-exposure of mouse skin to the anti-inflammatory agent fluocinolone acetonide, antioxidants and enzyme (phospholipase A2 and lipoxygenase) inhibitors lowered the peroxidation response to subsequent exposure to TPA. Phospholipid peroxidation products may be useful markers of oxygen radical production in TPA-exposed mouse skin with possible relevance to tumor promotion.

Abstract
On the premise that bone response to exercise is locally controlled, we conducted a randomized trial to evaluate the effects of a 1-year training of psoas muscles (treatment group: TG) versus a 1-year training of deltoid muscles (control group: CG) on the lumbar trabecular bone mineral density (TBMD). TBMD was measured with computed tomography scan. Seventy-eight subjects were included and 67 completed the study. Intention to treat analysis revealed no significant change in TBMD from 0 to 12 months. Data analysis in the 67 remaining women, including both assiduous and nonassiduous subjects, revealed greater bone loss in CG than in TG although the difference was not significant. Similar analysis in a subgroup of subjects who performed the exercises assiduously (TG: n = 23, CG: n = 26) showed that the mean bone loss of all four vertebrae from 0 to 12 months was significantly greater in the CG (-8.87 +/- 12.75 mg/cm3, mean +/- SD) than in the TG (0.14 +/- 11.21 mg/cm3, mean +/- SD, P = 0.01). These results suggest that continuous 1-year psoas training can prevent lumbar bone loss in postmenopausal women and support the hypothesis of local action of physical activity.

Abstract
Four new cases of cranial echinococcosis are presented and the literature is reviewed. Young males are most commonly affected. Early cases present as an expansile osteolytic lesion in the diploe. The more advanced forms manifest as multilocular or unilocular destructive lesions with adjacent soft-tissue masses. Two patients with unilocular hydatid cysts recovered completely after surgery. One youth with the multilocular form died four months after operation. The other patient is well two years after surgery. The location, anatomical forms of the lesion, and the importance of early diagnosis are stressed.
