Authors: Gharamaleki Ali Afaghi , Moaddab Seyyedreza , Darbouy Mojtaba , Ansarin Khalil , Hanifian Shahram 
Published: January 2019

Background: Republic of Azerbaijan and Iran are two neighboring countries with high amount of travelling between them, different rates of TB and its resistance. These relationships could complicate the controlling of tuberculosis programs.
Objective: The study was conducted to determine the prevalence of tuberculosis (TB) resistance and its risk factors in the two geographically co-related regions.
Method: A total of 119Mycobacterium tuberculosis isolates from the patients of the target regions (Azerbaijan Rep. and Tabriz, Iran) were examined at the Central Tuberculosis Laboratory in Tabriz, Iran. The cultures and drug susceptibility tests was performed on Lowenstein-Jensen. All the isolates were categorized by MIRU-VNTR molecular method into clustered and un-clustered groups. The clustering as well as demographic data were analyzed to determine the risk factors contributing to TB resistance. The categorical data about the TB resistance were compared using a chi square test.
Results: 27.8 percent of isolates were resistant at least to one of the 1st line of anti-tuberculosis drugs. The prevalence of any drug resistance and MDR were 64.6 and 17.9 percent respectively for Azari isolates, where the rate of resistance to rifampin and isoniazid was higher than streptomycin and ethambutol. The corresponding figures for the isolates from Tabriz were 16.9 and 3.3 percent respectively.
Conclusions: The results of this comparative and cross-sectional study showed statistically significant differences in TB resistance between the isolates from the patients of Azerbaijan Rep. and Iran. According to the results, the rate of resistance to RMP, INH, and MDR was higher in Azerbaijan; consequently, nationality could be regarded as a risk factor of MDR, resistance to RMP and INH but not to SM and ETB. Other studied parameters did not contribute to TB resistance.

Introduction: Heavy metals (HM) are dangerous elements due to their toxicity and prevalence play an important role in the environmental pollution and hazards to health risk. Impact of HM at high concentrations may lead to the failures of urinary bladder (UB) structure and functions. The aim of our study was to determine the readaptive changes in the UB of the rats and effectiveness of vitamin E using after the long-term intake of the HMS mixtures.
Materials and Methods: We used mature male laboratory rats which were divided into three series with special experimental conditions after the influence of HM. The detailed analysis of the UB state was performed by using morphometric, spectrophotometric, histological and electron microscopy methods.
Results: We had determined that the long-term intake of HM caused the significant increase of their accumulation in the tissue and morphometric changes of UB. Obtained results after the cancelation of the HM effect demonstrate smooth morphological restructuring of the UB wall with the reduction of difference of accumulation and morphometric indicators with control. The adjustment of vitamin E during there adaptation period showed better result recovery and optimization of all parameters, but they haven’t completely returned to normal state.
Conclusions: The influence of HMS mixture led to significant negative effect on the UB at all stages of research. However, under the conditions of readaptation the tendency towards a certain stabilization of all indicators was observed, but they didn’t completely pass to the end of the study. The vitamin E using has caused the acceleration and improved the development of readaptive change after HM exposure.

Background: Gastric cancer-related deaths are among the leading causes of cancer-related deaths. Clinical trials with targeted agents continue in the treatment of stomach cancer, with randomized trials of chemotherapy to prolong survival in the treatment of metastatic gastric cancer. Metastatic stomach cancer treatment is also becoming increasingly personalized to the characteristics of the patient and tumor as it is in breast cancer.
Result: Trastuzumab has shown randomized trial (TOGA study) in c-erbB2 positive metastatic stomach and gastroesophageal junction adenocancer patients to prolong median survival.Immunohistochemically, the presence of cerbB2 positivity and scoring at the time of diagnosis or in the resection material suggests that patients, especially in the metastatic stage, is necessary. The grade (score) of Cebb2 positivity was more pronounced in adenocarcinomas especially located anatomically close to the gastroesophageal junction.
Conclusion: In our study, it was aimed to reveal the relationship between the demographic characteristics of patients who are candidates for treatment and the level of cerbB2 positivity and anatomic localization, especially in the metastatic stage if stomach and thyroid cancer are considered to be a common condition in our region.

Penyusunan studi kelayakan suatu usaha adalah merupakan langkah terakhir yang perlu dilakukan sebelum suatu usaha mulai dilaksanakan hingga sampai kepada keputusan bahwa gagasan usaha tersebut dapat dilaksanakan atau dibatalkan. Sebelumnya terlebih dahulu dilakukan identifikasi dan formulasi sampai dengan keputusan perlu tidaknya dilakukan studi kelayakan. Penyusunan studi kelayakan untuk usaha mikro, kecil dan menengah (UMKM) di negara berkembang termasuk di Indonesia masih sangat jarang dilaksanakan. Hal ini disebabkan antara lain karena : Kondisi modal terbatas sedangkan biaya untuk menyusun studi kelayakan relatif tinggi., Kesadaran dan pengetahuan akan pentingnya manfaat suatu studi kelayakan masih belum tumbuh dengan baik, Pengusaha masih beranggapan bahwa studi kelayakan hanya perlu untuk mengajukan dana kredit kepada bank saja. Aspek-aspek yang penting dan menentukan terhadap kelayakan suatu rencana usaha, adalah aspek teknis produksi, aspek pasar dan pemasaran, aspek hukum, aspek sosial ekonomi, aspek manajemen, aspek keuangan dan aspek lingkungan. Hasil analisis semua aspek tersebut di atas, harus sampai kepada kesimpulan kelayakan yang menyeluruh.
