المبحث الأول: ليلة ممطرة

المبحث الأول: ليلة ممطرة

قصيدة (ليلة ممطرة) " لنازک الملائكة " ([1])

الآن یا نجمي تغیب ولم یحن وقت الأفول؟ (التوارِ لو الغیاب)
ألآن واللیلُ الجمیل یریق ضوءک في الحقول؟
والزھر، تحت اللیل، نشوانٌ([2]) بمشرقکِ الجمیل؟ 
والنھرُ، والشطآن([3])، تضحکُ تحت أشجار النخیلُ

ألآن تغربُ؟ یا لمأساۃِ الجمال الذابل
یا نجمي المآسور في کفّ الضباب الشامل
یا فیلسوف اللیل، یا سرّ الوجودِ الذاھل([4])
عَبَثاً أناشیدي إلی أضواءِ نجم آفل

عبثاً سھرتُ اللیل أرنو([5]) والتفجّعُ([6]) غالبي([7])
أتزوّدُ النظر الأخیر إلی ضیاک([8]) الشاحب([9])
وأصوغ ألحان الرثاء على صباك الشاحب
وأحوکُ من دمعي الضیاء لکلّ نجمٍ غارب


رحماک یا نجمي الجمیل متی نھایۃ لیلتي؟
ومتی ستنقشع([10]) الغیومُ وتستریح کآبتي([11])؟ 
قد شاق قلبي أن أحسُّ الصمتُ تحت خمیلتي([12])
وتجوبُ([13]) عیناي الفضاء وفي یدي قیثارتي

ما زلتُ أنتظر السکون ولیس غیرُ صدی المطر
والریحُ في سمع المساء تئنّ ما بین الشجرَ
لا طیرَ یمرحُ في الحقول ولا أریج ولا زَھَر
لا شيء غیر صراخ رعدٍ ھاتفٍ بأسی البشَر

ومن الظلام تصاعدت آھاتُ قُمري([14])الغصون
ذھبت بمسکنہِ([15]) الریّاح وعزّہ المأوی([16]) الحنون
حیرانُ، مرتعشُ الجناح، مجرّح([17]) تحت الدّجون
رحماکَ یا ربّ العواصفِ، حسبُنا المطر الھَتون([18])

أین الفضاۃ الحلو؟ أین الصحو([19])؟ أین سنا([20]) النجوم؟
من جمّع المطر الکئیب، وبثّ في الليل الغیوم؟
یا ریحُ رفقاً...

المقال الدينى عند محمود تيمور

Mehmood Taimur، A famous and well known literary figure of Egypt، when started his writing career، besides many literary works، he has penned down many essays too. He has written on different topics including the religious one. His religious writings come in the category of religious essays as their topics are purely religious. His religious essays encompass the following aspects: Love of Religion: He was bred and brought up in a religious family and learnt religious principles. So his essays are imbued in religious spirit. He regards love of religion not a mere part but the very essence of creed. He firmly believes that love of religion and country are the indispensable part of one’s belief. Love of God: His heart was saturated with the love of God. The sighs he heaved from his heart in his religious essays are the clear proof of his love of God. Love of Prophet (PBUH): He believes that you can never have love of God in your heart without the love of His Holy Prophet. Such kind of love is incomplete. He thinks that personality of the Holy Prophet(PBUH) is the living practical example of Holy Quran. Love of Quran: Mehmood Taimur has made clear that the Quran is the miracle of Holy Prophet(PBUH). Quran had influenced his heart deeply. He always meditated on Quran and the recitation of Quran after morning prayer was his daily routine. In short having been raised in religious atmosphere، his heart was free of all vices. On seeing such character traits، every reader may infers the conclusion that his s essays are truly religious in their spirit.

Rna Interference Based Therapeutic Interventions for Leukemias

Leukemia, a heterogeneous group of hematological malignancies, continues to cause significant morbidity and mortality despite decades of research and development. Chromosomal aberrations are the main cause of leukemia and lead to the generation of fusion/chimeric genes, resulting in activation of proto-oncogenes and suppression of tumor-suppressor genes. Incidence of different aberrations associated with different leukemias varies in different regions of the world and the data from population based studies in South Asia, including Pakistan, are lacking. The expression of chimeric/fusion genes can be detected using sensitive molecular methods like reverse transcriptase polymerase chain reaction (RT-PCR) and dot blot hybridization. In this study, classic BCR-ABL t(9;22) variants (e13a2 and e14a2) were detected in 96% of CML patients, while one of the patient possessed a unique e13-1a BCR-ABL variant. A total of 68 patients of paediatric ALL, were screened by RT-PCR to determine the relative frequency of t(9;22), t(12;21), t(1;19), and t(4;11,). Translocation (9;22) was seen in 2/68 (3%) and t(1;19) in 2/68 (3) children. Seven children showed t(12;21) while 8 showed t(4;11) translocations. In AML patients, t(8;21) was found in 4/21 patients while t(1;19) was seen in only one of the patient out of 21 screened. Thus, there appears to be a significant under representation of the fusion transcripts for TEL-AML, a good prognostic marker, in this study, unlike in the West, where it is seen in 35% of children with ALL. This, together with the generally increased leukemic burden seen in Pakistani patients, may explain in part, the poor treatment outcome reported. Conventional therapeutic approaches for leukemias include chemotherapy, radiation therapy, interferon therapy, stem-cell transplantation and surgery but their application is limited due to their side effects. The advent of RNA interference (RNAi) technology has opened the door to previously unrefined methods of therapeutic interventions. Gene targeting of the chimeric genes by small interfering RNA is an ideal way to kill tumor cells specifically, while leaving the normal cells unaffected. In case of CML, the over- expressed protein, tyrosine kinase, from BCR-ABL fusion genes, trigger malignant transformation and abnormal proliferation of the cells. Although targeting the BCR-ABL tyrosine kinase activity by imatinib mesylate has rapidly become first-line therapy, drug resistance suggests that combination therapy directed to a complementing target may significantly improve treatment results. To identify such potential targets, we used lentivirus-mediated RNA interference (RNAi) as a tool for functional genomics in human leukemic as well as murine hematopoietic cell lines. Expression of STAT1 and STAT3 proteins was successfully knocked down using specific shRNAs targeting STAT1 and STAT3 mRNA. RNAi-mediated reduction of STAT1 and STAT3 protein expression inhibited BCR-ABL–dependent (K562) but not cytokine-dependent (32D) cell proliferation. The data indicate that BCR-ABL expression may affect the function of normal signaling molecules. Targeting these molecules may harbor significant therapeutic potential for the treatment of patients with CML.
