Fraxinus xanthoxyloides is a perennial shrub belonging to family Oleaceae, traditionally used for malaria, jaundice, pneumonia, inflammation, and rheumatism. Our study is aimed to assess the total phenolics (TPC), flavonoids (TFC), terpenoids contents (TTC) and antioxidant profiling of F. xanthoxyloides methanol bark extract (FXBM) and its fractions, hexane, chloroform, ethyl acetate and aqueous, along with high-performance liquid chromatography with diode-array detection (HPLC-DAD). Further, the antioxidant and pulmonary protective potential was explored against carbon tetrachloride (CCl 4 )-induced CCl4-induced pulmonary tissue damage in rats. The highest TPC, TFC and TTC were found in FXBM (133.29 � 4.19 mg/g), ethyl acetate fraction (279.55 � 10.35 mg/g), and chloroform fraction (0.79 � 0.06 mg/g), respectively. The most potent antioxidant capacity was depicted by FXBM (29.21 � 2.40 μg/mg) and ethyl acetate fraction (91.16 � 5.51 μg/mg). The HPLC-DAD analysis revealed the predominance of gallic, chlorogenic, vanillic and ferulic acid in FXBM. The administration of CCl 4 induced oxidative stress, suppressed antioxidant enzymes' activities including catalase, peroxidase, superoxide dismutase, glutathione peroxidase, glutathione-S-transferase, and glutathione reductase. Further, it increased thiobarbituric acid reactive substances (TBARS) and H 2 O 2 levels, induced DNA injuries and reduced the total protein and glutathione content in lung tissues. The treatment of rats with FXBM restored these biochemical parameters to the normal level. Moreover, the histopathological studies of lung tissues demonstrated that FXBM protected rats' lung tissues from oxidative damage restoring normal lung functions. Thus, F. xanthoxyloides bark extract is recommended as adjuvant therapy as protective agent for patients with lung disorders.
Pituitary stalk interruption syndrome (PSIS) is a distinct and rare clinical entity responsible for congenital hypopituitarism resulting in deficiency of pituitary hormones with deficiency of the growth hormone (100%) and gonadotropins (97.2%) being its most common presentation at the time of hospital encounter (Wang et al., 2015).Isolated sparing of thyroid-stimulating hormone (TSH) with deficiency of the remaining anterior pituitary hormones may be present in PSIS, as is true in our case. Therefore, it should be kept in mind at the time of examination in suspected cases of PSIS.
BackgroundDifferentiation of Brain fungal abscess from brain glioblastoma is very important. Treatment strategies are different in both cases. Glioblastoma needs different surgical planning as compared with abscess. We hypothesized that preoperative MRI brain will help in differentiation.MethodsA retrospective study was carried out at Aga Khan University Hospital Karachi. Data from 2007 to 2017 was retrieved from Medical records using ICD-9 coding. 90 patients (47 males and 43 females; age range 10–70 years) with aggressive grade IV brain lesion and fungal abscess was selected and their preoperative MRI data were retrieved. The apparent diffusion coefficient (ADC) maps were reconstructed from diffusion-weighted imaging DWI data. The mean ADC value and standard deviation of glioblastoma and fungal abscesses were calculated. Postoperative biopsy results were used as gold standard.The analysis of data was done to test statistically significant differences between glioblastoma and fungal brain abscess. Receiver operating characteristic (ROC) curve was used to determine the cut-off point with highest accuracy that was used to differentiate malignancy from infection. The statistical analysis of data was done using SPSS® v. 19.ResultsThe mean (±standard deviation) ADC value of fungal brain abscess (826.040 ± 94.97 × 0.001 mm2/sec) was significantly lower than that of glioblastoma (1,462.800 ± 163.66 × 0.001 mm2/sec). When an ADC value of 1,200 × 0.001 mm2/s used as a cutoff value for differentiating fungal abscess from glioblastoma the best result was obtained with an accuracy of 85%, sensitivity of 81%, specificity of 88%, negative predictive value of 80%, and positive predictive value of 90%.ConclusionADC value is a noninvasive promising imaging parameter that can be used for differentiation of fungal brain abscess and glioblastoma on preoperative scan. The cut-off value with best accuracy in our study was 1,200 × 0.001 mm2/s. Disclosures All authors: No reported disclosures.
Southeast Asian countries have seen substantial economic growth over the years, but they have not been able to maintain environmental quality at the same time. Non-renewable sources constitute a significant proportion of energy consumption in the ASEAN which can have repercussions for long-term sustainable development. While the impacts of energy consumption and economic growth on environmental quality have been studied before, literature is quiet about the nexus between globalization, renewable and non-renewable energy, economic growth, and CO2 emissions in the ASEAN context. To fill in this gap in the literature, the present study estimates the effect of globalization, economic growth, and renewable and non-renewable energy on CO2 emission under the umbrella of the EKC hypothesis over the 1995 to 2020 period. Due to the presence of cross-sectional dependence and heterogeneity of slope parameters, second-generation techniques of co-integration, unit root, and long and short-run estimations are used. According to the findings of CS-ARDL estimation, non-renewable energy and globalization contribute to environmental deterioration, whereas renewable energy has a positive contribution to environmental quality improvement in ASEAN countries. Moreover, the findings prove the validation of the EKC hypothesis in the selected economies. The study concludes that the region is developing at the expense of environmental quality while also pursuing enormous globalization initiatives. The policy implications and directions of the findings for sustainable development are discussed.
A 6-month-old boy presented with painless right hemiscrotal swelling. The scrotal ultrasound revealed a cerebrospinal fluid hydrocele caused by the migration of a ventriculoperitoneal shunt (VPS) catheter tip into the right hemiscrotum and associated undescended left testis. Earlier, he underwent a VPS placement for hydrocephalus secondary to neonatal bacterial meningitis and ventriculitis. The patient was treated with bilateral herniotomy, left-sided orchidopexy and repositioning of VPS into the peritoneal cavity.
