Chloroquine has gained great emphasis in the treatment of malaria. This study sought experimentally to determine the histomorphological and weight changes in the testes of male mice infected with Plasmodium berghei and treated with chloroquine. The study used 30 Swiss mice divided into five groups. Group 1 is Control that was not infected with Plasmodium berghei and not treated with chloroquine as control, Group 2 is Plasmodium (Plasmodiul berghei) Infected animals but not treated, Group 3 is Plasmodium Infected animals + Chloroquine (5mg/kg), Group 4 is Plasmodium Infected animals + Chloroquine (10mg/kg) and Group 5 is Plasmodium Infected animals + Chloroquine (15mg/kg). The mice were treated for 7 days after parasitaemia was confirmed and the Group 2-5 testes studied with reference to Group 1. The results showed that the Group 2 showed a little distortion, difference in spermatogenic activities and increased cellular activities; Group 3 showed large, convoluted tubules, moderate number of spermatids and large interstitial spaces, Group 4 showed Large seminiferous tubules, large spermatids, increased distortion and group 5 showed shrinking of seminiferous tubules, degeneration of interstitial cells of Leydig cells and Sertolic cells with spermatids. Groups 1-5 showed no significant effect in in body weights and testes weights of Swiss mice. Plasmodium berghei (malaria) and chloroquine have effects on histomorphological structures of Swiss mice testes but not on their teste’s weights. The testicular section from Swiss mice infected with malaria and treated at various doses when compared with the Control (Group 1) showed some moderate distortion in some structures like seminiferous tubules, connective tissues between the tubules, lumen and interstitial spaces. It can be deducted that Plasmodium berghei which caused parasitaemia in mice could cause a little tissue effect on mice if not treated.

Aim: This study was designed to investigate the effect of ethanolic extracts of the leaves of Emilia sonchifolia on the haematological parameters and histomorphology of the liver of male Swiss albino mice infected with Plasmodium berghei berghei (Pbb).Material and Methods: 35 mice were divided into; Group 1 (control) given normal saline 0.3 ml, Group 2 passaged with Pbb only, Group 3 passaged with Pbb, and then treated with Coartem®, Group 4 treated with E. sonchifolia 325 mg/kg only, Group 5 treated with E. sonchifolia 650 mg/kg only, Group 6 passaged with Pbb then treated with E. sonchifolia 325 mg/kg, while Group 7 was passaged with Pbb then treated with E. sonchifolia 650 mg/kg. Pbb was passaged intraperitoneally, while the test drug and extracts was given via orogavage once daily.Results: The result showed significantly (P<0.001) reduced RBC parameters at in Group 5 treated with 650 mg/kg similar with Group 2 compared to Group 1, while there was significant (P<0.01) increased WBC and differentials in Parasitized groups compared with Group 1. The micrographs showed slightly inflamed nuclei in Group 4, with few nuclei shrinkage Group 5, whereas in the parasitized groups treated with the extract there appeared to be hepatoprotection compared to Group 2.Conclusion: In conclusion, the extract promotes erythropoiesis at 325 mg/kg, but was haemolytic at 650 mg/kg, and exerts its effect possibly through an agonistic and a synergistic activity of its rich bioactive ingredients. It showed mild toxic effect in the histomorphology of the non-parasitized mice at 325 mg/kg and 650 mg/kg, and also appeared to offer hepatoprotection in parasitized mice compared to the parasitized group that had no treatment.

Background: We hypothesized that perioperative HbA1c influenced the pattern and outcomes of Lower Extremity Amputation (LEA). Methods: A retrospective analysis was conducted for all patients who underwent LEA between 2000 and 2013. Patients were categorized into 5 groups according to their perioperative HbA1c values [Group 1 (<6.5%), Group 2 (6.5-7.4%), Group 3 (7.5-8.4%), Group 4 (8.5-9.4%) and Group 5 (≥9.5%)]. We identified 848 patients with LEA; perioperative HbA1c levels were available in 547 cases (Group 1: 18.8%, Group 2: 17.7%, Group 3: 15.0%, Group 4: 13.5% and Group 5: 34.9%). Major amputation was performed in 35%, 32%, 22%, 10.8% and 13.6%, respectively. Results: The overall mortality was 36.5%; of that one quarter occurred during the index hospitalization. Mortality was higher in Group 1 (57.4%) compared with Groups 2-5 (46.9%, 38.3%, 36.1% and 31.2%, respectively, p=0.001). Cox regression analysis showed that poor glycemic control (Group 4 and 5) had lower risk of mortality post-LEA [hazard ratio 0.57 (95% CI 0.35-0.93) and hazard ratio 0.46 (95% CI 0.31-0.69)]; this mortality risk persisted even after adjustment for age and sex but was statistically insignificant. The rate of LEA was greater among poor glycemic control patients; however, the mortality was higher among patients with tight control. Conclusion: The effects of HbA1c on the immediate and long-term LEA outcomes and its therapeutic implications need further investigation.

AbstractOestradiol, an important hormone in follicular development and endometrial receptivity, is closely related to clinical outcomes of fresh in vitro fertilization-embryo transfer (IVF-ET) cycles. A supraphysiologic E2 level is inevitable during controlled ovarian hyper-stimulation (COH), and its effect on the outcome of IVF-ET is controversial. The aim of this retrospective study is to evaluate the association between elevated serum oestradiol (E2) levels on the day of human chorionic gonadotrophin (hCG) administration and neonatal birthweight after IVF-ET cycles. The data of 3659 infertile patients with fresh IVF-ET cycles were analysed retrospectively between August 2009 and February 2017 in First Hospital of Zhengzhou University. Patients were categorized by serum E2 levels on the day of hCG administration into six groups: group 1 (serum E2 levels ≤ 1000 pg/mL, n = 230), group 2 (serum E2 levels between 1001 and 2000 pg/mL, n = 524), group 3 (serum E2 levels between 2001 and 3000 pg/mL, n = 783), group 4 (serum E2 levels between 3001 and 4000 pg/mL, n = 721), group 5 (serum E2 levels between 4001 and 5000 pg/mL, n = 548 ), and group 6 (serum E2 levels > 5000 pg/mL, n = 852). Univariate linear regression was used to evaluate the independent correlation between each factor and outcome index. Multiple logistic regression was used to adjust for confounding factors. The LBW rates were as follows: 3.0% (group 1), 2.9% (group 2), 1.9% (group 3), 2.9% (group 4), 2.9% (group 5), and 2.0% (group 6) (P = 0.629), respectively. There were no statistically significant differences in the incidences of neonatal LBW among the six groups. We did not detect an association between peak serum E2 level during ovarian stimulation and neonatal birthweight after IVF-ET. The results of this retrospective cohort study showed that serum E2 peak levels during ovarian stimulation were not associated with birth weight during IVF cycles. In addition, no association was found between higher E2 levels and increased LBW risk. Our observations suggest that the hyper-oestrogenic milieu during COS does not seem to have adverse effects on the birthweight of offspring after IVF. Although this study provides some reference, the obstetric-related factors were not included due to historical reasons. The impact of the high estrogen environment during COS on the birth weight of IVF offspring still needs future research.

AbstractTo avoid winter scarcity of fresh goat milk, simple methods of advancing the season of kidding would be commercially valuable. A combination of long-day light treatment followed by melatonin is successful but other aspects of seasonality including coat growth are also reset. To investigate whether effects on breeding season and coat growth can be dissociated, British Saanen dairy goats (no. = 30) were randomly allocated to one of six groups. Control goats were untreated. Goats in the other five groups received 2 months of treatment with 20 h light: 4 h darkness (20L: 4D) and were then given 3 mg melatonin orally at 16.00 hfor 2 months. The treatments started on 11 January (group 1), 29 March (group 2), 14 June (group 3), 30 August (group 4) and 8 November (group 5). Weekly blood samples were taken for the measurement of progesterone to monitor ovarian activity and prolactin. Side patches (10 cm ×10 cm) were clipped monthly from alternate sides and weighed to measure coat growth. The onset of ovarian activity was advanced from a median date of 15 November in controls to 24 May in group 1 (P < 0·01), 16 August in group 2 (P < 0·05) and 18 October in group 3 (? < 0·05). Groups 4 and 5 showed no significant change in the onset of oestrus (median onset dates 8 November and 1 November, respectively). Group 1 goats came into season again with controls in November. In all except group 5, treatment interacted with time to affect significantly the growth of the coat. The pattern of coat growth was most altered (P < 0·001) in groups 1 and 2. This was associated with effects on plasma prolactin concentrations of light stimulation and melatonin suppression. Group 1 goats resynchronized with control goats to show a coat of normal weight in the winter following treatment. Division of milking goat herds into spring and autumn kidding groups is, therefore, a practical possibility, but effects on overall milk yield require study.

A total of 130 barrows and 113 gilts were slaughtered over a range of liveweights from 65.6 to 143.9 kg. These animals were randomly assigned to six different liveweight groups (group 1, less than 79.5 kg; group 2, 79.5 through 93.1 kg; group 3, 93.2 through 106.7 kg; group 4, 106.8 through 120.4 kg; group 5, 120.5 through 134.0 kg; and group 6, 134.1 kg and over) and utilized to evaluate the effects of slaughter weight and sex on palatability and cooking properties. The composite results indicated that the slaughter weight of both barrows and gilts can, from a practical standpoint, be increased to take advantage of potential economic advantages without meaningfully altering cooking losses or palatability attributes.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

Background A serum autoantibody biomarker, NMO-IgG has been recently described in patients with Devic's neuromyelitis optica (DNMO) and so called `high-risk' patients for this disease. Our objectives were to replicate the test and to assess its usefulness. Methods Indirect immunofluorescence with a substrate of adult rat cerebellum and midbrain was used to identify the distinctive NMO-IgG staining pattern. We tested masked sera from 26 patients with DNMO (group 1), 21 patients with idiopathic acute transverse myelitis (ATM) (group 2), 21 patients with bilateral and/or recurrent idiopathic optic neuritis (group 3), 52 patients with classical multiple sclerosis (MS) (group 4), 36 patients with HTLV-1 infection (group 5) and 7 patients with miscellaneous disorders (group 6). Results We identified a vascular staining pattern typical of NMO-IgG. This particular staining was observed in 14/26 samples in group 1, 7/21 in group 2 (positive only in longitudinally extensive acute transverse myelitis: 7/13), 4/21 in group 3 (with bilateral loss of vision in all seropositive cases), 5/52 in group 4 (none of them suggestive of DNMO), 0/36 in group 5 and 0/7 in group 6. Sensitivity of the test was 54% considering detection of DNMO (group 1), and specificity was respectively 94% and 90% when considering groups 4, 5 and 6 altogether or group 4 of MS patients only. Conclusion Detection of NMO-IgG is contributory to the distinction of DNMO and `DNMO high-risk' syndromes from MS. This test may allow earlier diagnosis and help therapeutic decisions.

Objective(s). The major challenge encountered to decrease the milliamperes (mA) level in X-ray imaging systems is the quantum noise phenomena. This investigation evaluated dose exposure and image resolution of a low dose X-ray imaging (LDXI) prototype comprising a low mA X-ray source and a novel microlens-based sensor relative to current imaging technologies.Study Design. A LDXI in static (group 1) and dynamic (group 2) modes was compared to medical fluoroscopy (group 3), digital intraoral radiography (group 4), and CBCT scan (group 5) using a dental phantom.Results. The Mann-Whitney test showed no statistical significance(α=0.01)in dose exposure between groups 1 and 3 and 1 and 4 and timing exposure (seconds) between groups 1 and 5 and 2 and 3. Image resolution test showed group 1 > group 4 > group 2 > group 3 > group 5.Conclusions. The LDXI proved the concept for obtaining a high definition image resolution for static and dynamic radiography at lower or similar dose exposure and smaller pixel size, respectively, when compared to current imaging technologies. Lower mA at the X-ray source and high QE at the detector level principles with microlens could be applied to current imaging technologies to considerably reduce dose exposure without compromising image resolution in the near future.
