Abstract
A highly sensitive low-cost strain sensor was fabricated in this research study based on microdispensing direct write (MDDW) technique. MDDW is an additive manufacturing approach that involves direct deposition of functional material to the substrate. The devices were printed directly onto a polymeric substrate by optimizing the fabrication parameters. A composite of silver and carbon was used as active sensor material where both materials in the composite have opposite resistance temperature coefficients. The ratio of materials in the composite was selected so that the effect of temperature on the resistance of overall composite was canceled out. This resulted in achieving temperature compensation or inherent independence of the strain sensor resistance on temperature without requiring any additional sensors and components. The sensor was further encapsulated by electrospray deposition, which is also an additive manufacturing approach, to eliminate the effect of humidity as well. Electrical and morphological characterizations were performed to investigate the output response of the sensors and their physical and structural properties. An analog signal conditioning circuit was developed for seamless interfacing of the sensor with any electronic system. The sensor had an excellent gauge factor of 45 and a strain sensitivity of 45 Ω/μɛ that is higher than most of the conventional strain sensors. The sensor's response showed excellent temperature and humidity compensation reducing the relative effect of temperature on the resistance by ∼99.5% and humidity by ∼99.8%.

Abstract
Insomnia is a common sleep disorder without effective therapy and can affect a person's life. The mechanism of the disease is not completely understood. Hence, there is a need to understand the targets related to insomnia, in order to develop innovative therapies and new compounds. Recently, increasing interest has been focused on complementary and alternative medicines for treating or preventing insomnia. Research into their molecular components has revealed that their sedative and sleep-promoting properties rely on the interactions with various neurotransmitter systems in the brain. In this review, the role of 5-hydroxytryptamine (5-HT) in insomnia development is summarized, while a systematic analysis of studies is conducted to assess the mechanisms of herbal medicines on different 5-HT receptors subtypes, in order to provide reference for subsequent research.

Abstract
BACKGROUND Adolescence is when an individual undergoes development and growth. Many studies suggest variations in the number and size of blood cells during this period in various individuals. The full blood count (FBC) is often the starting point of medical investigations, which help diagnose a wide range of illnesses, infections, and diseases. This study aimed to report the mean FBC values and compare them by gender and ethnicity, using blood results from the thalassemia screening programme in Seremban District, Malaysia. MATERIALS AND METHODS This cross-sectional study used secondary data from the thalassemia screening programme on Form 4 students aged 15-16 years from January 2018 to October 2018 by the Seremban District Health Office, Malaysia. These students participated in the thalassemia screening programme in which their blood samples were taken for FBC analysis. The data were extracted for this study. RESULTS There were statistically significant gender-based differences for total white blood cell (WBC) count, neutrophils, lymphocytes, mixed WBC, and platelets. It was also observed that ethnic-specific differences were statistically significant for RBC count, platelets, platelet distribution width and mean platelet volume. CONCLUSION This study was able to report the mean FBC values among Malaysian adolescents with respect to their gender and ethnicity, of which there is a lack of published data.

Abstract
Physids belong to Class Gastropoda; belong to Phylum Mollusca and being bioindicators, intermediate hosts of parasites and pests hold a key position in the ecosystem. There are three species of Genus Physa i.e. P. fontinalis, Physa acuta and P. gyrina water bodies of Central Punjab and were characterized on the basis of molecular markers High level of genetic diversity was revealed by polymorphic RAPD, however SSR markers were not amplified. The multivariate analysis revealed polymorphism ranging from 9.09 percent to 50 percent among the three Physid species. Total number of 79 loci were observed for the three species under study and 24 loci were observed to be polymorphic. These RAPD fragment(s) can be developed into co dominant markers (SCAR) by cloning and can be further sequenced for the development of the Physa species specific markers to identify the introduced and native species in Pakistan.

Abstract
Physids belong to Class Gastropoda; Phylum Mollusca have important position in food web and act as bio indicators, pests and intermediate host. Being resistant these are called cockroaches of malacology. Physid snails were collected from different water bodies of Faisalabad (Punjab) and were identified up to species using morphological markers. The morphometry of the specimens was carried out with the help of a digital Vernier caliper in millimeters (mm) using linear measurement of shell characters. Linear regression analysis of the AL/SW ratio vs AL and SL/SW ratio vs AL indicated that allometric growth exists only in Physa acuta when compared with P.gyrina and P. fontinalis. This study will lead to assess the status of the Physid species in Central Punjab. The Principal component analysis shows that the Component 1 (Shell Length) and component 2 (Shell Width) are the most prolific components and nearly 80 percent of the identification. The distance between P. acuta and P. fontinalis is 5.4699, P. acuta and P. gyrina is 7.6411, P. fontinalis and P. gyrina is 16.6080 showing that P. acuta resembles with P. fontinalis, and both these specimens donot resemble with P. gyrina. P.acuta is an invasive species and shows bioactivity making it a potent candidate for bioactive substances.

Abstract
BackgroundEgo defense mechanisms, defined by Freud as unconscious resources used by the ego to reduce conflict between the id and superego, are a reflection of how an individual deals with conflict and stress. Vaillants’ proposed Hierarchy of Defenses states that mature defenses are associated with better adaptive functioning and health, as opposed to immature defense which are correlated negatively with measures of adaptive adult functioning.ObjectivesThis study assesses the prevalence of various ego defense mechanisms employed by medical students of Karachi, which is a group with higher stress levels than the general population.MethodsA questionnaire based cross-sectional study was conducted on 682 students from five major medical colleges of Karachi in November 2006. Ego defense mechanisms were assessed using the Defense Style Questionnaire(DSQ-40) individually and as grouped under Mature, Immature, and Neurotic factors.ResultsNeurotic defenses had a higher mean score(5.62) than Mature(5.60) and Immature(4.78) mechanisms. Immature mechanisms were more commonly employed by males whereas females employed more Neurotic mechanisms than males. Neurotic and Immature defenses were significantly more prevalent in first and second year students. Mature mechanisms were significantly higher in students enrolled in Government colleges than Private institutions (p< 0.05).ConclusionsNeurotic mechanisms are more commonly encountered than Mature or Immature mechanisms among medical students of Karachi, and this could reflect greater stress levels than the general population. Employment of these mechanisms was associated with female gender, enrollment in a private medical college, and students enrolled in the first 2 years of medical school.

Abstract
The aim of this study was to investigate the synergistic hepatoprotective effect of lignans from Fructus Schisandrae chinensis (LFS) with Astragalus polysaccharides (APS) on chronic liver injury in male Sprague-Dawley rats. Subcutaneous injection of 10% CCl(4) twice a week for 3 months resulted in significantly (p<0.001) elevated serum alanine aminotransferase (ALT), asparate aminotransferase (AST), alkaline phosphatase (ALP) activities compared to controls. In the liver, significantly elevated levels (p<0.001) of malondialdehyde (MDA), lowered levels of reduced glutathione (GSH) (p<0.05) and catalase (CAT) (p<0.001), superoxide dismutase (SOD) (p<0.01)were observed following CCl(4) administration. 'LFS+ASP' treatment of rats at doses of 'LFS (45mg/kg)+APS (150mg/kg)' and 'LFS (135mg/kg)+APS (450mg/kg)' displayed hepatoprotective and antioxidative effects than the administration of either LFS or APS, as evident by lower (p<0.005 or 0.001) levels of serum ALT, AST, ALP and hepatic MDA (p<0.001) concentration, as well as higher SOD (p<0.05 or 0.005), CAT activities(p<0.01 or 0.005), GSH concentration (p<0.05 or 0.005) compared to the toxin treated group. Histopathological examinations revealed severe fatty degeneration in the toxin group, and mild damage in groups treated with 'LFS+APS' were observed. The coefficients drug interaction (CDI) between each individual drug and their combination (at the same dose of their single treatment) of these foregoing parameters were all less than 1, indicating that LFS and APS display hepatoprotective and antioxidant properties and act in a synergistic manner in CCl(4) induced liver injury in rats.

Abstract
We retrospectively analyzed the results of 75 living-related pediatric renal transplants performed at our center between January 1986 and December 1999. The major causes of end-stage renal disease (ESRD) were glomerulonephritis (26%) and nephrolithiasis (16%), while the etiology was unknown in 50%. The mean age of the recipients was 12 yr (range 6-17 yr) and that of the donors was 39 yr (range 20-65 yr). The majority (73%) of donors were parents. Eighty five per cent of donors were one-haplotype matched and the rest identical. Immunosuppression was based on a triple drug regimen. Thirty per cent of recipients were rapid metabolizers of cyclosporin A (CsA) (area under the curve [AUC]: < 6,000 ng/mL/h), while 16% were slow metabolizers (AUC: > 8,000 ng/mL/h). Forty three (57%) children encountered 59 rejection episodes, the majority of which (59%) were recorded in the first month post-transplant. Seventy-four per cent of the rejection episodes were steroid sensitive and the rest, except two, were resolved by therapy with antithymocyte globulin (ATG) or orthoclone thymocyte 3 (OKT3). After a mean follow-up of 37 months, 17 (22%) grafts had chronic rejection and 76% of these recipients had previously experienced acute rejection episodes. The overall infection rate was high, necessitating two hospital admissions/patient/year. The majority (53%) of the infections were bacterial. Urinary tract infections (UTIs) were seen in 17 (23%) recipients. Twelve of these had ESRD as a result of stone disease and eight grafts were lost because of UTIs. Eight per cent of recipients developed tuberculosis (TB), and extra-pulmonary lesions were seen in 50%. Surgical complications were encountered in eight patients. Free medication to all recipients and parental support ensured a compliance rate of 93%. Baseline growth deficit was seen in children of the two groups studied (the 6-12 yr and 13-17 yr age-groups), with Z-scores of - 2.39 and - 2.12, respectively. No growth catch-up was observed at 12 and 24 months in either group. Post-donation complications were seen most commonly in donors > 50 yr of age and included: proteinuria (> 300 mg/24 h, four patients), hypertension (three patients), and diabetes (one patient). Twenty-four grafts were lost, 54% as a result of immunological and the rest as a result of non-immunological causes, and 17 recipients died during the follow-up period. Infections were the main cause of patient and graft loss. Overall 1- and 5-yr graft and patient survival rates were 88% and 65%, and 90% and 75%, respectively.

Abstract
It has been suggested that girls and women coming from a Muslim background in the Asian sub-continent are disadvantaged in the educational sphere. In this study two particular aspects of this suggested disadvantage are investigated. First, the importance of educating males rather than females and secondly, the issue of parental and husband's control over the rights of women to education and work. Twenty-six Muslim females living in a large Scottish town but of a Pakistani Punjabi background were interviewed in depth. The findings, that these women considered that it is as important to educate girls as it is to educate boys, and that they acquiesced in parental and husband's control over the rights of females to be educated and work, are discussed within a cross-cultural perspective. It is concluded that such issues cannot be isolated from traditional values about the importance of upholding family honour.

Abstract
A 5-day study, forming the initial part of two 32-day clinical trials and involving 22 unipolar depressed inpatients, was designed to determine the relationship between response to sleep deprivation and 24-hour urinary MHPG levels. A statistically significant, positive relationship was noted between the sleep deprivation, modified total HAM-D scores and MHPG levels at postsleep deprivation, indicating that the greater the severity of depression during sleep deprivation the higher were the MHPG levels after the sleep deprivation period.
