Pink bollworm, Pectinophora gossypiella (Saunders) is one of the serious insect pests of cotton crop attacking fruiting bodies which may result in loss of yield and damage to cotton fibre quality. In the present study comparative resistance of Bt. and non-Bt. cotton varieties was evaluated for management of P. gossypiella. Different Bt. cotton varieties, IR-901, FH-142, MNH-886, NIBGE IR 3701, CIM-602 and Tarzan-1 containing (Cry1Ac) and non-Bt. varieties, CRIS-134, CRIS-342, CRIS-129, CRIS-613, FH-1000 and FH-901were used in the study during two consecutive years (2015 and 2016) at district Sanghar, Sindh, Pakistan. The results indicated that the maximum attack of P. gossypiella larvae was recorded on IR-901 and minimum CIM-602 in Bt. cotton varieties. However, in non-Bt. cotton, maximum attack was observed on FH-901 and minimum on CRIS-129. Biological parameters of P. gossypiella on Bt. and non-Bt. cotton varieties were evaluated under laboratory conditions. The result revealed that the larval period and pupal weight, adult longevity and female reproduction rate of P. gossypiella were significantly lower on Bt. cotton as compared to non-Bt. However, there was no significant difference in pupal period between Bt. and non-Bt. cotton. The larval % parasitization of P. gossypiella was recorded by collection of P. gossypiella larvae from cotton field and ginning factories. Four parasitoids i.e., Tachinid sp, Apanteles sp, Habrobracon sp and Magasillia sp found parasitizing the larvae. The maximum incidence of parasitization was observed in cotton field as compared to cotton ginning factories. The present study also monitored the post-harvest population of P. gossypiella in different cotton ginning factories from three locations of district Sanghar such as Jhol, Sanghar and Shahdadpur. The results revealed that the maximum larval population was recorded from Sanghar and Shahdadpur. Maximum P. gossypiella adult population by using synthetic sex pheromone traps was recorded at Jhol as compared to Sanghar and Shahdadpur cotton ginning factories. The maximum mean larval and adult P. gossypiella population was observed in the months of October and November. Light and synthetic sex pheromone traps were installed in Bt. and non-Bt. cotton field to monitor population of P. gossypiella. The results showed that the highest population of P. gossypiella males was captured from non-Bt. as compared to Bt. cotton through light and synthetic sex pheromone traps. The maximum population was trapped in the month of September and October in both years. The regression analysis indicated that P. gossypiella adults had negative and non-significant relation with temperature and positive and significant relation with relative humidity. Different plant extracts and insecticides were tested in the fields on Bt. and non-Bt. cotton crop for the management of P. gossypiella. The highest reduction percentage of P. gossypiella larvae was recorded on tobacco treated plot followed by neem and datura in both Bt. and non-Bt. cotton crops. The effect of varietal resistance of (Bt. and non-Bt. cotton varieties) was not recorded in 2015 but in 2016 the effect of tobacco and Bt. cotton on larval population was significant. However, the application of different insecticides (triazophos, spintoram and profenophos+cypermethrin) on Bt. and non-Bt. cotton crop indicated that the maximum pest population reduction was recorded in triazophos followed by spintoram and profenophos+cypermethrin treated plots in both Bt. and non-Bt. cotton.

مولانا محمد منظور نعمانی

مولانا محمد منظور نعمانی
گزشتہ مہینے کا معارف اشاعت کے مرحلے میں تھا کہ یہ افسوسناک خبر ملی کہ مولانا محمد منظور نعمانی ۴، ۵؍ مئی کی درمیانی شب میں انتقال فرماگئے۔ انا ﷲ وانا الیہ راجعون۔
اس قحط الرجال میں مولانا جیسے حکمت دین سے واقف صاحب فہم و بصیرت اور مدبر عالم، قوم کے درد مند مصلح اور ملت کے ہمدرد و غم گسار کا اٹھ جانا کس قدر المناک سانحہ ہے۔
مولانا ایک عالم و مصنف اور صاحب سلوک و عرفان بزرگ ہی نہ تھے بلکہ زمانے کے نبض شناس، وقت کے تقاضوں اور حالات سے باخبر اور عاقبت بیں بھی تھے جن کا عمل اس پر تھا کہ:
نکل کر خانقاہوں سے ادا کر رسمِ شبیری
کہ فقرِ خانقاہی ہے فقط اندوہ و دل گیری
وہ مذہبی، اصلاحی، قومی، ملی، تعلیمی اور اجتماعی جدوجہد کے ہر محاذ پر سرگرم اور متحرک دکھائی دیتے تھے، انہیں مسلمانوں کی موجودہ پستی و زبوں حالی کا پوری طرح احساس بھی تھا اور وہ اس کے ازالے کے لیے نہایت فکر مند بھی رہتے تھے، آزاد ہندوستان میں جن مسائل نے مسلمانان ہند کی زندگی تلخ اور مکدر کر رکھی ہے، ان پر شور و غوغا مچانے لچھے دار باتیں اور دھواں دار تقریریں کرنے اور پُرجوش تحریریں لکھنے والے تو بہت سارے لوگ ہیں لیکن ان پر مولانا کی طرح تڑپنے، بے چین ہوجانے، درد و کرب خلش و اضطراب میں مبتلا ہونے والے بہت کم لوگ ہیں، وہ مسلمانوں کی فلاح و بہود کے لیے دعا و مناجات میں بھی مصروف رہتے تھے اور ملک کے گوشے گوشے کی خاک بھی چھانتے رہتے تھے، ان کے گریہ شب اور دعا ہائے سحر گاہی سے گھبرا کر ابلیس بھی یہ کہتا رہا ہوگا کہ ؂
خال خال اس قوم میں اب تک نظر آتے ہیں وہ

پاکستان کے مشترکہ خاندانی نظام میں رہائش سے متعلقہ مسائل اور ان کا حل (اسلامی تعلیمات کی روشنی میں ایک جائزہ) Issues of Accommodation in the joint family system of Pakistan and their solution (An analytical study in the context of the Islamic teachings)

A family is the fundamental unit of society. Every society has the presence of a family. The start of a family's life is entirely dependent on matters of co. human relations. All such human relationships are entrenched in islamic sharia as a sacred bond of nikah, in which a husband and wife become a part of the world in the form of a family's collective result. Husband and wife are the most fundamental pillars of society, and their affection and companionship provides a source of stability for them and also a refuge for coming generations.A  family consist of husband ,wife and their children . The family life is begins with marriage, after marriage every woman wants to have her own separate home where all the requirements of privacy are met. Islam has placed the entire responsibility of livelihood on men..But in our society there are two types of family system joint and separate family system. In Pakistan The joint family system is prevalent. The people of the subcontinent are not only adopting this system but they are  also feel proud of it . In the present article the joint family  system has facing many challenges. One of them is accommodation. In this article will focus on  what is the basic concept of accommodation in joint family systems and its solution in Islami teachings. It is critical for the husband and wife to have a home where no one can  interfere on their personal matters. This interference is very much in our society.Which husband and wife facing many  problems. And due to this conditions, the relationship of husband and wife is also affected. Key Words: Joint family system, Issues of Accommodation, Pakistani society, Islamic teachings.

Genetic Analysis in Coronary Heart Disease Patients and Dynamics of Nuclear Calcium in Isolated Cardiomyocytes

Coronary Heart Disease (CHD) is one of the leading killers of human beings in Pakistan. Outcome of complex diseases like CHD is determined by interaction between multiple factors including the genetic factors, most importantly. To scrutinize the association of various genetic polymorphisms [rs7025486(A/G), rs1333049(G/C), rs6922269(G/A), rs2943634(C/A), rs599839(A/G), rs17465637(C/A), rs501120(C/T) and rs17228212(C/T)] with the risk of CHD in Pakistani population, the present investigation was designed. Although these genetic variants have been already explored for their association with CHD in European populations, the unique architecture and genetic composition of Pakistani population warrant an independent trial in this population. Samples for patients were collected from different hospitals in Lahore and Gujranwala. Samples for controls were randomly collected from various Government and private institutes and hospitals. A detailed questionnaire was administered for acquisition of desired information and for taking informed consent. A total of 645 samples (435 cases and 210 controls) were collected out of which 6% were excluded based on positive screening for Hepatitis B, Hepatitis C or HIV. The remaining 606 samples (403 cases and 203 controls) were utilized for biochemical (lipid profile) and genetic analysis. Results for the lipid profiling imply that the levels of various lipoproteins and triglycerides were impaired in a higher percentage of cases as compared to controls pointing towards an association between dyslipidaemia and the atherosclerosis which underlies CHD. Findings of the present exploration pertaining to the genetic polymorphisms indicate that for rs7025486(A/G), increased risk of CHD was on margin level in GA carriers (Odds ratio: 1.72; 95% Confidence interval: 1.223- 2.428) and frequency of risk allele [A] was higher in cases as compared to controls (Cases: 0.45; Controls: 0.41). For rs1333049(G/C), those carrying CC genotype were at margin of increased risk for CHD (Odds ratio: 1.65; 95% Confidence interval: 1.096-2.476). Carriers of GC were experienced to be at risk margin of CHD only in men (Odds ratio: 1.18; 95% Confidence interval: 0.805-1.730) and in the combined data analysis (Odds ratio: 1.12; 95% Confidence interval: 0.800-1.571). The frequency of risk allele [C] was observed as being elevated in case subjects than xiv controls (Cases: 0.55; Controls: 0.45). For rs6922269(G/A), elevated risk of CHD was at margin level in bearers of AA genotype (Odds ratio: 1.36; 95% Confidence interval: 0.523-3.523). In addition, those possessing GA genotype were also found to be at risk margin of CHD (Odds ratio: 1.76; 95% Confidence interval: 1.183-2.630). Besides, frequency of risk allele [A] was comparatively raised in case subjects (Cases: 0.20; Controls; 0.13). Results pertinent to rs2943634(C/A) indicate that carriers of CC were at increased risk margin of CHD (Odds ratio: 1.53; 95% Confidence interval: 1.058-2.221) and that, the risk allele frequency [C] was lower in controls than in cases (Cases: 0.87; Controls; 0.80). With regards to rs599839(A/G), increased risk margin of CHD was experienced in AA carriers (Odds ratio: 1.72; 95% Confidence interval: 1.156-2.566) and the risk allele frequency [A] observed a decrease in controls as compared to cases (Cases: 0.90; Controls; 0.84). As far as rs17465637(C/A) is concerned, vulnerability to CHD was revealed to be at margin level in CC carriers (Odds ratio: 1.40; 95% Confidence interval: 0.993-1.961). This observation stayed the same when the data was analyzed for MI patients only (Odds ratio: 1.68; 95% Confidence interval: 1.163-2.442) In addition, only the female AA carriers were divulged to be at an increased risk margin of CHD (Odds ratio: 1.13; 95% Confidence interval: 0.367-3.471). Further, frequency of the risk allele [C] was higher in case subjects than in control subjects (Cases: 0.65; Controls; 0.60). In relation to rs501120(C/T), TT genotype carriers were found to be at elevated risk margin of CHD (Odds ratio: 1.29; 95% Confidence interval: 0.917-1.816). Besides, CT carriers were also at margin of increased risk of CHD (Odds ratio: 1.05; 95% Confidence interval: 0.750-1.484). Furthermore, cases experienced a comparatively increased frequency of the risk allele [T] (Cases: 0.68; Controls; 0.61). For rs17228212(C/T), frequency of the CT carriers was extremely low (< 5 %) in our sample population and CC carriers were completely absent implying that the results were of little potential significance keeping in view the low frequency of C allele. Besides the genetic analysis of CHD patients, some of the experiments included here pertinent to dynamics of nuclear calcium in isolated cardiomyocytes were conducted as part of a project entitled "Nuclear Calcium and Gene Regulation in the Remodeled Heart" which aimed at investigating the role of nuclear calcium in cardiac remodeling and pursuing it as a therapeutic approach. The results highlight that xv nuclear calcium transient manifests a slower release time but a similar uptake time when compared with cytoplasmic calcium. Independent release of nuclear calcium was also observed. Addition of 2-APB, a blocker of IP3 receptor mediated calcium release, lead to a decrease in the amplitude of calcium transient in the cytoplasm but not in the nucleus at both 1 and 2 Hz. No effect of the drug could be ascertained on calcium release or reuptake time. Furthermore, 2-APB caused a shortening of the calcium transient in both nucleus and cytoplasm of isolated cardiomyocytes. Isolation of adult mouse ventricular cardiomyocytes done as a part of the work on mice expressing VSFP2.3 targeted at the investigation of this protein as an optogenetic tool for studying cardiac activity is also a part of the present research. The findings relevant to this research indicate that genetic polymorphisms play a significant role in modifying the risk of CHD and that, modulation of nuclear calcium can be pursued as an effective target for attenuation of cardiac remodeling which is associated with CHD.
