Abstract
This study aimed to prepare three imine derivatives (1, 2, and 3) via a condensation reaction of phenyl hydrazine, 2-hydrazino pyridine, and 4-methoxy aniline with 4-formyl pyridine. Electron impact mass spectrometry (EIMS), proton nuclear magnetic resonance (1H-NMR), ultraviolet-visible (UV-Vis) and Fourier transform infrared (FTIR) spectroscopy were utilized for the characterization. The chemosensing properties of [4((2-phenyl hydrazono)methyl) pyridine] (1), [2-(2-(pyridin-4-ylmethylene)hydrazinyl) pyridine] (2), and [4-methoxy-N-yl methylene) aniline] (3) imino bases have been explored for the first time in aqueous media. The photophysical properties of chemosensors (1, 2, and 3) were examined by various cations (Na+, NH4+, Ba+2, Ni+2, Ca+2, Hg+2, Cu+2, Mg+2, Mn+2, and Pd+2). The chemosensor (1) showed very selective binding capability with copper ions at low concentrations (20 μM) without the influence of any other mentioned ions. The maximum complexation was noted with Cu+2 and 1 at pH between 7 to 7.5. The stoichiometry binding ratio between chemosensor (1) and Cu+2 was determined by Job's plot and it was found to be 1:2. The current study explored the use of these Schiff bases for the first time as heterocyclic chemosensors. DPPH radical scavenging, urease enzyme inhibition activities, molecular docking simulation, and density functional theory (DFT) analysis of compounds 1, 2, and 3 were also conducted.

Abstract
Present study was conducted to study seasonal abundance and distribution of dragonflies in upper Siran valley district Mansehra Pakistan. To collect data, eleven localities were visited for three consecutive years (2016-2018). Results come up with a sum of 300 specimens identified under three families, eight genera and twenty species. Highest seasonal abundance recorded during summer and spring were 80.67% and 13.33% respectively while minimum 6.00% was recorded during early autumn. Dominant species observed were, Orthetrum chrysis (14.00%), followed by O. gluacum (12.00%), Palpoleura sexmaculata sexmaculata (11.33%) and O. cancellatum cancellatum (8.00%). However the highest population of dragonflies was found in Munda Gucha with a percentage of 11.33 followed by Jabbar (11.00%) and Sachan (9.67%). The lowest populations were recorded in Suham (6.00%), Dadar (7.67%) and Jabori (7.67%). The surveyed valley showed diverse Anisopterous fauna and thus further extensive surveys are recommended that can come up with more important species from the area.

Abstract
Poor storage conditions provide favorable environment to stored grain pests for their growth. The bio-pesticides are the best alternatives to synthetic pesticides. Present study was conducted to compare toxicity of Rubus fruticosus and Valeriana jatamansi against granary weevil, Sitophilus granarius and subsequent changes in enzyme activity responsible for grain damage. In current research 5 g of R. fruticosus fruit and V. jatamansi rhizome powders were tested separately against S. granarius, in 50 g wheat whole grains for seven days in comparison with the control. The enzymatic activity of malate dehydrogenase and α-amylase was observed in the cellular extracts of S. granarius. The insects were crushed and homogenized in phosphate-buffer solution and centrifuged at 10000 rpm for 5 minutes. For the enzymatic measurement supernatant was tested; the spectrophotometer was adjusted at 340 nm. The reagents were mixed and incubated at 25 °C for five minutes. The cuvettes were placed in the experimental and reference sites of spectrophotometer and recorded the change in absorbance for 3-4 minutes. There was 5.60% and 14.92% reduction in the activity of malate dehydrogenase in R. fruticosus and V. jatamansi, treated insects, respectively. The alpha amylase enzyme activity was 6.82% reduced and 63.63% increase in R. fruticosus and V. jatamansi, treated insects, respectively. Present study addresses that both plant powders are effective against granary weevil by altering enzyme activities so both the plant powders can be used as bio-pesticides against the stored grains pests.

Abstract
AIM The burden of Type 2 diabetes is alarmingly high in South Asia, a region that has many genetically diverse ethnic populations. Genome-wide association studies (GWAS) conducted largely in European populations have identified a number of loci predisposing to Type 2 diabetes risk, however, the relevance of such genetic loci in many South Asian sub-ethnicities remains elusive. The aim of this study was to replicate 49 single nucleotide polymorphisms (SNPs) previously identified through GWAS in Punjabis living in Pakistan. METHODS We examined the association of 49 SNPs in 853 Type 2 diabetes cases and 1945 controls using additive logistic regression models after adjusting for age and gender. RESULTS Of the 49 SNPs investigated, eight showed a nominal association (P < 0.05) that also remained significant after controlling for the false discovery rate. The most significant association was found for rs7903146 at the TCF7L2 locus. For a per unit increase in the risk score comprising of all the 49 SNPs, the odds ratio in association with Type 2 diabetes risk was 1.16 (95% CI 1.13-1.19, P < 2.0E-16). CONCLUSION These results suggest that some Type 2 diabetes susceptibility loci are shared between Europeans and Punjabis living in Pakistan.

Abstract
The aim of this study was to investigate trends in road traffic crashes (RTCs) managed by an emergency service, Rescue 1122, in 2011 in Punjab, Pakistan. RTC data were collected from 35 districts of Punjab and reviewed retrospectively. Data analysis revealed that the service responded to 12 969 RTC emergencies during August 2011 (Ramadan), compared with an average of 11 573 RTCs per month from January to August 2011. The younger age group (11-27 years) was victims in 29% of RTCs; 39% were due to speeding and 43% occurred in peak rush hours (14:00-18:00) before iftar (breakfast).Results of the study showed that Rescue 1122 faced more RTCs during Ramadan compared with the preceding months. Road safety is an important public health issue in Pakistan. Although there have been great improvements in roads in the past few years, much work needs to be done to deal with mounting trends in RTCs. Public awareness, political will and stringent law enforcement are key factors.

Abstract
PURPOSE Since 1943 [1], only 45 patients of squamous cancer of the rectum have been reported in the published reports and the largest series to date consists of 12 patients. Reports suggest that the primary treatment is surgical resection but, in the light of nonsurgical advances in the treatment of anal squamous cell carcinoma (SCC), we present a review of the literature and report six patients treated by chemoradiation therapy (CRT). METHOD A literature search was undertaken using the keywords squamous cell, epidermoid, basaloid and cloacagenic and cancer of rectum and colon to provide evidence for this discussion from studies of surgery, radiation therapy and CRT in rectal SCC. A prospective database of the Mount Vernon Cancer Centre, UK was searched from 1995 to 2005 for patients diagnosed with pure SCC of the rectum. RESULTS Six patients with histologically confirmed primary SCC of the rectum were treated with primary combination chemo-radiotherapy according to protocols used for SCC of the anal canal over a 15-year period. Surgery was avoided in four, and they remain disease-free on follow-up. CONCLUSIONS Primary CRT, as currently utilized in anal cancer, can be extended to primary SCC of the rectum.

Abstract
Very long-chain acyl-CoA dehydrogenase (VLCAD) catalyses the initial step of mitochondrial beta-oxidation of long-chain fatty acids with a chain length of 14 to 20 carbons. Deficiency of VLCAD activity has been associated with a range of phenotypes, including a severe lethal form presenting in the infantile period and a milder variant with onset in childhood. Varying rates of residual enzyme activity partly explain the heterogeneity in presentations. Here we report the course of disease in a pair of monozygotic twin sisters who were diagnosed in their late forties during an evaluation for rhabdomyolysis and fatigue. Interestingly, the patients' complaints were most severe during puberty and declined significantly after the menopause. The basis for this observation is uncertain, but may be related to hormonally-mediated changes in lipid metabolism that may occur at these times. As metabolic decompensation can be associated with significant morbidity, timely diagnosis of VLCAD deficiency is important. The introduction of appropriate dietary measures (i.e. avoidance of fasting, long-chain fat restriction and supplementation with medium-chain triglycerides) greatly reduces the likelihood of complications.

Abstract
OBJECTIVE Three thousand five hundred and forty-nine patients are waiting for a colonoscopy in the Kent and Medway cancer network. New guidelines identify those who require surveillance for polyp, cancer, IBD and family history. Our hypothesis was that most of the patients on the waiting list would no longer need a colonoscopy if the new guidelines were applied. PATIENTS AND METHODS We compared the ACPGBI guidelines for screening/surveillance colonoscopy with the indications in 411 notes of one hospital's waiting list and removed patients as appropriate. In the second part of study we analysed 192 patients attending colonoscopy in seven hospitals in the region and calculated the potential impact of the guidelines on our waiting lists. RESULTS Of 411 patients on the waiting list in one hospital, only 98 (24%) needed to remain on the list. 142 (34%) were cancelled completely. One hundred and seventy-one (42%) were taken off the 'waiting' list and rebooked for a later date since according to the new guidelines the colonoscopy was not due yet. Of 192 colonoscopies actually performed during the study period in 7 hospitals of Kent and Medway cancer network, 72 (38%) were for surveillance. Two thirds of those were not in line with the guidelines. As a result of implementing the guidelines, waiting times for diagnostic colonoscopy fell from 12 to 4 weeks for urgent, and from 40 to 15 weeks for routine referrals. CONCLUSION A quarter of the 8000 colonoscopies performed annually in our region are unnecessary when compared to the guidelines. More than three quarters of our waiting list could be removed by reviewing the notes. Implementing the guidelines in one cancer network would save pounds 1 million per year even on conservative estimates of pounds 500 per colonoscopy. It would also reduce the waiting times for diagnostic colonoscopy.

Abstract
A gene for reading disability has been localized by nonparametric linkage to 6p21.3-p22 in several published reports. However, the lack of an uninterrupted genomic clone contig has made it difficult to determine accurate intermarker distances, precise marker order, and genetic boundaries and hinders direct comparisons of linkage. The search and discovery of the hemochromatosis gene (HFE) led to the creation of a bacterial artificial chromosome (BAC) and P-1 derived artificial chromosome (PAC) contig that extended physical maps 4 Mb from the MHC toward pter and localized new markers in that region [10-12]. Using this contig, we localized 124 sequence tagged sites, expressed sequence tags, and short tandem repeats including most of the markers in linkage with reading disability phenotypes, succinic semialdehyde dehydrogenase, GPLD1, prolactin, and 18 uncharacterized genes. This new contig joins and extends previously published physical maps to span the entire chromosome 6 reading disability genetic locus. Physical mapping data from the complete contig show overlap of the published linkage peaks for reading disability, provide accurate intermarker distances and order, and offer resources for generating additional markers and candidate genes for high resolution genetic studies in this region.

Abstract
Changing the major histocompatibility complex (MHC) class I phenotype is a pivotal strategy of tumor cells to circumvent an effective immune response and is associated with tumor progression in cancer patients. Epithelial cells in bone marrow have been detected in various tumor types, but the clinical observation that only a portion of the patients with a positive bone marrow status develops solid bone metastasis suggests a certain molecular equipment of the isolated tumor cells as a prerequisite for metastatic formation. In the present study the prognostic impact of the MHC class I phenotype of disseminated epithelial cells in bone marrow was evaluated in a cohort of 30 curatively resected (R0) patients without distant metastases (M0) (designated R0M0) who had minimal residual disease. Immunocytochemical analysis using the alkaline/anti-alkaline immunogold double staining procedure revealed a heterogeneous MHC class I expression profile [monoclonal antibody (mAb) W6/32] of the epithelial cells (mAb CK2). In 16 patients (53.3%) all epithelial cells were human leukocyte antigen (HLA) class I-positive (CK2+//W6/32+ phenotype). Eight patients (26.7%) showed complete loss of the HLA class I molecules (CK2+//W6/32- phenotype) and in 6 patients (20%) partial loss of HLA class I expression was found (CK2+//W6/32+ and - phenotype). CK2+ cells with the HLA class I negative phenotype (CK2+//W6/32- phenotype and CK2+//W6/32+ and - phenotype) were often derived from poorly differentiated (G3) primary breast carcinomas (p = 0.036) and were associated with short survival of the R0M0 patients (follow-up 15-98 months, log rank p = 0.072). These findings support the necessity to develop immmunotherapeutic strategies leading to the restoration of MHC class I positive phenotype.

Abstract
A bioactivity directed isolation of the methanolic extract of the fresh, uncrushed leaves of Nerium oleander showing a central nervous system (CNS) depressant effect in mice has been undertaken. As a result, four CNS depressant cardenolides including a new cardenolide, neridiginoside and three known constituents, nerizoside, neritaloside and odoroside-H, have been isolated which exhibited CNS depressant activity in mice at a dose of 25 mg/kg. The structure of neridiginoside was elucidated as 3 beta-O-(D-diginosyl)-5 beta, 14 beta-dihydroxy-card-20(22)-enolide, using spectroscopic methods including one-dimensional and two-dimensional NMR (COSY-45, NOESY, J-resolved, HMQC and HMBC). The known compounds have been indentified through spectral studies and comparison of data with those reported in the literature.

Abstract
Two new cardenolides, 3 beta-O-(D-2-O-methyldigitalosyl)-14 beta-hydroxy-5 beta-carda-16,20(22)-dienolide (1) and 3 beta-hydroxy-8,14-epoxy-5 beta-carda-16,20(22)-dienolide (2), and two known cardenolides, 3 beta-O-(D-digitalosyl)-14 beta-hydroxy-16 beta-acetoxy-5 beta-card-20(22)-enolide (3) and 3 beta-O-(D-digitalosyl)-14 beta-hydroxy-5 beta-card-20(22)-enolide (4), have been isolated from the leaves of Nerium oleander following a bioactivity-directed isolation of the MeOH extract, which showed central nervous system (CNS) depressant activity in mice at a dosage of 50 mg/kg i.p. Their structures were established on the basis of chemical and spectral data. Compounds 1, 3, and 4 were found to exhibit sedation in mice at a dosage of 25 mg/kg, although 2 had no effect on the CNS of mice at a dosage of up to 50 mg/kg.

Abstract
Fresh, undried and uncrushed leaves of Nerium oleander were subjected to methanol extraction and bioassay directed fractionation. This led to the isolation of two purified fractions namely, B-1 and B-3. Fractions B-1 and B-3 were studied with respect to their actions on the central nervous system and behavior pattern in mice. Both fractions were found to produce reduction in locomotor activity, rota rod performance and potentiation of hexobarbital sleeping time. These fractions also showed analgesic activity. When tested against picrotoxin induced convulsions fraction B-1 showed 40% protection, while fraction B-3 exhibited 60% protection against bicuculline induced convulsions. These findings suggest that both fractions possess a CNS depressant action.
