background and objective: the main causes of nocturnal hypoxemia are pulmonary diseases or sleep related breathing disorders. in overlap syndrome, the co-existence of chronic obstructive pulmonary disease (copd) and ob-structive sleep apnea (osa), blood oxygen alteration, and hypercapnia may be more severe. we aimed to study hypox-emia markers in osa patients with or without copd. materials and...
vehicle exhaust is a major source of exposure to polycyclic aromatic hydrocarbons (pahs) found in the urban atmosphere. newsagents usually work close to heavy traffic flow. the purpose of this study was to assess the breathing zone exposure of newsagents to pahs found in the urban atmosphere of tehran city during summer and autumn seasons and comparing the levels of exposure in both seasons.fif...
lip is an important aspect of facial features affecting ones personality. a deformity of the lip characterized by excessive tissue sagging below the usual giving it thicker wider appearance is referred to as double lip. it is a rare occurrence with a proposed male predilection. this article is a report of a 20 years old male with this deformity who presented with the complaint of difficult spee...
This paper presents a new lip detection method based-on normalized RGB chromaticity diagram. The method consists of three stages: face detection, lip region localization and lip detection. The popular Viola-Jones face detection technique is employed in the face detection stage. In the lip detection stage, lip color is extracted using our novel color segmentation method that exploits the distrib...
Liposomes coated with N-trimethyl chitosan to improve the absorption of harmine in vivo and in vitro
In this study, harmine liposomes (HM-lip) were prepared through the thin-film hydration-pH-gradient method and then coated with N-trimethyl chitosan (TMC). Particle size, zeta potential, entrapment efficiency, and in vitro release of HM-lip and TMC-coated harmine liposomes (TMC-HM-lip) were also determined. Sprague Dawley rats were further used to investigate the pharmacokinetics in vivo. Reten...
Visual information from lip shapes and movements helps improve the accuracy and robustness of a speech recognition system. In this paper, a new region-based lip contour extraction algorithm that combines the merits of the point-based model and the parametric model is presented. Our algorithm uses a 16-point lip model to describe the lip contour. Given a robust probability map of the color lip i...
LOU M/Wsl rats inoculated s.c. with 10(4) immunoglobulin immunocytoma cells have a palpable tumor at Day 17. Doxorubicin (DXR) has been entrapped in negatively charged liposomes (lip- DXR) composed of egg phosphatidylcholine, cholesterol, and phosphatidylserine and in positively charged liposomes (lip+ DXR) composed of phosphatidylcholine, cholesterol, and stearylamine. DXR, lip- DXR, and lip+ ...
در این پروژه، امکان پساب زدایی پساب رنگرزی منسوجات نساجی حاوی رنگ آزو astarzon red fbl، در بیوراکتور بستر ثابت که با قطعه های سنگ آذرین (kissiris) به قطر تقریبی 1 سانتیمتر انباشته شده، با استفاده از قارچ ریسه سفید فانروکایت کرایسوسپوریوم بررسی شده است. فانروکایت کرایسوسپوریوم، گونه ای از قارچهای مخرب چوب و محصولات چوبی می باشد که به واسطه برخورداری از یک سیستم آنزیمی شامل آنزیمهای اکسیداتیو ل...
کربونیک آنهیدراز (ca) آنزیمی حاوی فلز روی میباشد که واکنش برگشت پذیر تبدیل گاز دی اکسید کربن به بی کربنات را کاتالیز میکند. این آنزیم برای سیستم های زیستی و از جمله بدن انسان بسیار مهم است. در این کار تحقیقاتی به بررسی عملکرد آنزیم کربونیک آنهیدراز در این واکنش توسط نظریه تابعی چگالی(dft) در سطحb3lyp و با سری پایهg* 31-6 در فاز گاز و حلال به روش pcm پرداخته شده است و متغیرهای ترمودینامیکی (?h...
BACKGROUND The Millard method of unilateral cleft lip repair has been associated with a short lip and a flattened nose on the cleft side. The aim of this study was to determine the need for revision surgery following repair of unilateral cleft lip repair at the Komfo Anokye Teaching Hospital. METHOD Satisfaction with facial appearance (upper lip, nose and general facial appearance) was assess...
