Indo-Pak subcontinent is the world‘s largest cultivator of Brassica. It constitutes 33 % of the world‘s land, cultivated under rapeseed and mustard crops. Weeds ecology of Brassica crops i.e., Brassica juncea (L.) Czern. (Mustard), B. rapa L. and B. napus L. (Rapeseed) were explored for elaborating the weed species profile in districts of Abbottabad, Haripur and Mansehra. Weeds are the part of dynamic ecosystem growing in cultivated crop or ordinary environment. Its flora has not been evaluated quite often from its ecological point of view and phytosociological classification because of its deteriorating impacts on economic crops. Therefore, its flora in Brassica crop of the aforementioned districts was quantitatively analyzed under the impact of various environmental variables. Quadrate quantitative ecological techniques were used for sampling of weeds vegetation. Phytosociological attribute and physiognomic characteristics of each weed species were recorded at each quadrate.Physicochemical properties of soil were measured at each station and compared with quantitative and synthetic characteristics of weed communities. A total of 50 weed species (44 dicot & 6 monocot) were recorded from Brassica crops belonging to 20 different plant families. The topmost abundant weed of the Brassica crop was Euphorbia helioscopia, Galium aparine and Coronopsus didymus while, Lapsana communis, Scandix pecten veneris and Parthenim hysterophorus were the rare weed species with minimum importance values. Euphorbiaceae was the topmost dominant family followed by Poaceae and Brassicaceae in the studied area. All the collected weeds belong from therophytes life form category. Species belonging to Constancy Classes IV-V were Euphorbia helioscopia, Coronopus didymus and Fumaria officinalis appearing close to 50 % of the stands in Mustard and Rapeseed fields. While Anagallis arvensis, Avena sativa and Galium aparine present in less than 50% of the stands (Class: III - IV). Species revealed to Class I, were present either in Mustard or Rapeseed fields. It appears that the synthetic characters followthe pattern of Quantitative Characers upto certain extent. Result of soil characteristics revealed that the soil of Abbottabad and Mansehra districts were mostly silty clay loam different from Haripur and Havelian regions along with silt loam soil condition. Furthermore, soil of Abbottabad and Haripur has maximum amount of N-NO3, pH as compared to Mansehra. Potassium (K) and Phosphorus (P) concentration were higher in soil of Mansehra and Haripur rather than Abbottabad Havelian regions.Regarding, Zinc (Zn) and Manganese (Mn) concentration which is higher in Haripur and Mansehra respectively. Electrical conductivity (EC) was higher in all three regions except Haripur.While, increased amount of nitrate concentration in soil is due to the abundantly presence of nitrogen fixation weeds in the fields. The aforementioned finding i.e., weeds of Brassica crops, their general profile and distribution in different farming systems of the area will provide a baseline for devising weed management strategies in the studied area. It will also open a new venue of research for Brassica crops improvement through the scientific ways of weed eradication
ڈاکٹر راجندر پرشاد سابق صدر جمہوریہ ہند ڈاکٹر راجندر پرشاد کی موت ہندوستان کا ایک بڑا قومی حادثہ ہے، وہ اپنے قومی و ملکی خدمات کے لحاظ سے صف اول کے لیڈروں میں تھے، ہندوستان کی جنگ آزادی میں ان کے بڑے کارنامے ہیں، چمپارن کی مشہور ستیہ گرہ کے گویا ہیرو تھے، وہ گاندھی جی کے خاص تربیت یافتہ اور ان کے معتمد علیہ تھے، ان میں ان کی بہت سی اخلاقی خوبیاں موجود تھیں، جو آخر تک قائم رہیں، ہندوستان کی آزادی کے بعد کانگریس کے بہت سے لیڈروں کے خیالات اور کردار میں تبدیلی ہوگئی ہے، ان سے ان کا دامن محفوظ تھا، وہ کانگریس کے پرانے اصولوں پر برابر قائم رہے، اور اپنے جلیل القدر عہدے کی ذمہ داریوں کو بھی بڑی خوبی کے ساتھ نباہا، طبعاً بڑے شریف اور مرنجان مرنج تھے اور قومی و ملکی معاملات میں ان کا دل بہت وسیع تھا، اس لیے کسی طبقہ کو بھی ان سے کوئی شکایت نہیں پیدا ہوئی، وہ پرانے کایستھ تھے اس لیے اردو اور فارسی تہذیب سے بہت اچھی واقفیت رکھتے تھے، اور بہت شستہ اردو بولتے اور لکھتے تھے، اور ان میں قدیم مشترک تہذیب کی بہت سی خوبیاں موجود تھیں، اس لیے ان کی موت مختلف حیثیتوں سے بڑا قومی سانحہ ہے۔ اور ان کا نام ہندوستان کی تاریخ میں ہمیشہ زندہ رہے گا۔ (شاہ معین الدین ندوی، مارچ ۱۹۶۳ء)
Breast carcinoma is among the most common malignancy in women. Objective: Aim of the present study was to evaluate the prognostic significance of iron expression in the biopsies of patients with breast cancer. Methods: 24 breast biopsies were studied. 19 cases were poorly differentiated, 5 cases were moderately differentiated and there was no well differentiated case. Iron, Estrogen receptor (ER), Progesterone receptor (PR), HER2 and Ki-67 immunohistochemical staining was performed for all these cases. Results: Among the 5 moderately differentiated cases, 3 (60%) were positive for iron staining and among 19 poorly differentiated cases, 11 cases (57.89%) were positive. More iron positive cases (7 out of 14) were triple positive belonging to Luminal B class. Out of 14 iron positive cases, 11 were positive for HER2, 10 for ER, 9 for PR and all positive for Ki-67. Conclusions: Iron deficiency in premenopausal and overload in post-menopausal women can contribute to the development of breast carcinoma. So, iron can be considered as a cheap and effective marker for the prognosis of breast cancer. Association between a risein iron levels and HER2 expression may providenewstrategy for breast cancer treatment.
This study focused on the high temperature tolerance of mungbean varieties using plexiglass canopy to increase the prevailing high temperature. The plant measurements were made for heat induced changes growth, photosynthetic pigments, gas exchange, osmolytes accumulation, oxidative stress and antioxidative response, shoot, root and seed nutrient and yield attributes at different growth stages. Data revealed that heat tolerance in mungbean was variable at three prime foliation and flowering stages. The varieties exhibiting prolific root system and leaf area (e.g., NM-2011 and NM-2006) were more tolerance to heat stress. Heat stress caused the loss of chlorophyll and inhibition of the leaf gas exchange. The tolerant varieties incurred a minimum loss of photosynthetic pigments; more importantly increased carotenoids contents were closely associated to heat tolerance. Among the studied osmolytes, the accumulation of soluble sugars and GB at flowering stage contribute greatly to heat tolerance in the studied varieties. Due to high temperature, the production of hydrogen peroxide (as reactive oxygen species) and malondialdehyde was seen, but the tolerant varieties produced minimum amounts of these oxidative stress metabolites, while the accumulation of phenolics, anthocyanin, and ascorbic acid were able to possibly protect the membrane especially in the tolerant varieties. The success of the tolerant varieties in displaying greater pod growth and seed yield characters appeared to be due maintenance of greater nutrient contents both in the shoot and root tissues especially under excessive high temperature stress. In conclusion, mungbean showed a large genetic variability for tolerance to heat stress at flowering and maturity stages. This implied that the varieties with a tendency to maintain greater nutrient contents was better able to withstand heat stress conditions. Among the studied attributes, the heat stress induced oxidative stress appeared to be a main reason for mungbean susceptibility to high temperature. Future studies will further our understanding on heat tolerance mechanisms and mungbean improvement programs for better growth in warmer areas.
