Background: The current study was designed to investigate the effect of supplementation of Flaxseed (Linumusitatisimum) oil on libido and semen quality of Nilli-Ravi buffalo bulls. Methods: In this study, 12 adult healthy bulls kept at the Semen Production Unit, Qadirabad district Sahiwal, were used. These bulls were divided into three equal groups, A, B and C. Group A was kept as control, while in groups B and C supplementation of feed was provided by using flaxseed oil @125 ml/day and 250 ml/day,respectively for 12 weeks. Two ejaculates per animal were collected at 0 day then 5th, 6th, 7th, 8th, 9th, 10th, 11th and 12th week of treatment. In this way a total 216 samples were taken, and each semen sample was evaluated for color, volume, mass activity, percent motility, sperm cell concentration per ml, percentage of live sperm, and plasma membrane integrity. Libido of bulls was also evaluated before every collection. Results: Analysis of data revealed that these parameters were significantly (P < 0.01) increased in flax oil treated animals as compared to control. Conclusion: It was concluded from the present study that flax seed oil has beneficial effects on reproductive health of buffalo bull.

Goumri-Said Souraya,Shah Mazhar Ali,Azam Sikander,Irfan Muhammad,Kanoun Mohammed Benali 한국물리학회 2023 Current Applied Physics Vol.49 No.-

Ternary selenide chalcogenide Tl3AsSe3 compound was identified as one of the most promising novel materials and potentially appropriate for multifunction applications. Current computational study is focused on computation of optical properties of Tl3AsX3 (X = S and Se) system where Modified Becke Johnson (mBJ) approximation is employed. The calculations of band structure revealed that both materials were indirect bandgap semiconducting materials with bandgap 1.5 eV and 1.9 eV respectively. The valence band maxima are mainly created because of Tl/As/S/Se(s/p/p/p) orbitals and conduction band is formed thanks to hybridizations of Tl/ As/S/Se(p) orbitals. The optical properties including complex dielectric function, reflectivity, energy loss function, refractive index, and real optical conductivity also calculated by using first-principles calculations. Our investigations explained that the two materials sustain their positive value of the refractive index and thus is the non-negative index of refractions, so these materials are active candidates for optoelectronic applications.

Background: Early onset breast cancer is associated with poor outcomes but variable results have been reported. It is a significant problem in Pakistani women but remains under reported. Breast conservation plays an important role in surgical management of this younger patient group. The objective of this study was to determine the outcome of breast conservative therapy in patients with early onset breast cancer in our population and compare it with their older counterparts. Materials and Methods: A review of patients with invasive breast cancer who underwent breast conservation surgery at Shaukat Khanum Cancer Hospital from 1997 to 2009 was performed. Patients were divided into two groups i.e. Group I age ${\leq}40$ and Group II >40 years. A total of 401 patients with breast cancer were identified in Group I and 405 patients in Group II. Demographics, histopathological findings and receptor status of the two groups were compared. The Chi square test was used for categorical variables. Outcome was assessed on basis of 10 year locoregional recurrence free survival (LRRFS), disease free survival (DFS) and overall survival (OS). For survival analysis Kaplan Meier curves were used and significance was determined using the Log rank test. Cox regression was applied for multivariate analysis. Results: Median follow up was 4.31 (0.1-15.5) years. Median age at presentation was 34.6 years (17-40) and 51.9 years (41-82) for the two groups. Groups were significantly different from each other with respect to grade, receptor status, tumor stage and use of neoadjuvant therapy. No significant difference was present between the two groups for estimated 10 year LRRFS (86% vs 95%) (p=0.1), DFS (70% vs 70%) (p=0.5) and OS (75% vs 63%) (p=0.1). On multivariate analysis, tumor stage was an independent predictor of LRRFS, DFS and OS. Conclusions: Early onset breast cancer is associated with a distinct biology but does not lead to poorer outcomes in our population.

Background: Triple negative breast cancer is associated with aggressive behavior and high risk of local and regional failure. Aggressive surgical intervention is considered suitable. This makes role of breast conserving therapy (BCT) debatable in these patients. The objective of this study was to compare outcome of BCT for triple negative versus non-triple negative breast cancer. Materials and Methods: Medical records of patients who underwent breast conserving therapy from 1999 to 2009 at Shaukat Khanum Cancer Hospital and had complete receptor status information were extracted. Patients were divided into triple negative breast cancer (TNBC) and non-TNBC. Patient characteristics, medical treatment modalities and adverse events were compared. Expected five year locoregional recurrence free, disease free and overall survival was calculated. The Cox proportional hazard model was used to identify independent predictors of outcome. Results: A total of 194 patients with TNBC and 443 with non-TNBC were compared. Significant difference was present for age at presentation (p<0.0001), family history (p=0.005), grade (p<0.0001) and use of hormonal therapy (p<0.0001). The number of locoregional failures, distant failures and mortalities were not significantly different. No significant difference was present in 5 year locoregional recurrence free (96% vs 92%, p=0.3), disease free (75% vs 74%, p=0.7) and overall survival (78% vs 83%, p=0.2). On multivariate analysis, tumor size, nodal involvement and hormonal treatment were independent predictors of negative events. Conclusions: Breast conserving therapy has comparable outcomes for triple negative and non-triple negative breast cancers.

Kim, Sung Bae,Sayeed, Ahmed,Villalon, Antonio H,Shen, Zhen Zhou,Yau, Tsz Kok,Shah, Mazhar Ali,Hou, Meng Feng,Thuan, Tran Van,Ba, Duc Nguyen,Chao, Tsu-Yi Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.2

Background: The Asia-Pacific Breast Initiatives (APBI) I and II registries were established to collect safety data for patients with early stage breast cancer receiving adjuvant docetaxel-based regimens in the Asia-Pacific region. Materials and Methods: Data from the two registries were combined to perform a safety analysis. Participants in the registry were women with early stage operable breast cancer with an intermediate or high risk of recurrence. These women received adjuvant chemotherapy that included docetaxel between 2006 and 2011. Adverse events (AEs) were recorded and analyzed. Results: Data were collected from 3,224 patients from 13 countries. The mean dose intensity of docetaxel was 24.1, 22.7, $25.1mg/m^2/week$ among patients receiving docetaxel-based monotherapy, combination therapy and sequential therapy, respectively. Granulocyte colony-stimulating factor (G-CSF) was given with docetaxel to 41.8% of women and 20.6% of women receiving prophylactic antibiotics. Adverse events were reported in 86% of patients (anthracycline-containing regimens vs. non-anthracycline regimens; 87% vs. 80%). The most common adverse events were alopecia, nausea, neutropenia, vomiting, and myalgia. Adverse events NCI CTCAE ${\geq}$Grade 3 were reported in 45.4% of patients. Serious adverse events were reported in 13% of patients, of which 2.5% led to study discontinuation. Forty-six deaths (1.4%) were reported, with no significant difference between regimens. Conclusions: The safety parameters of adjuvant docetaxel therapy used to treat sequential Asian women were comparable to those reported in clinical trials evaluating the role of adjuvant docetaxel. No unusual adverse events linked to Asia-Pacific region patients were observed.
