The postpharyngeal gland (PPG) is unique to ants and is the largest exocrine gland in their head. In queens of the pharaoh’s ant, Monomorium pharaonis , the gland contains approximately 15 finger-like epithelial extensions on each side and opens dorsolaterally in the posterior pharynx. In these ants the PPG morphology varies considerably according to age and mating status. The epithelial thickn...
Group III metabotropic glutamate receptors (mGluRs) are thought to modulate neurotoxicity of excitatory amino acids, via mechanisms of presynaptic inhibition, such as regulation of neurotransmitter release. Here, we describe (R,S)-4-phosphonophenylglycine (PPG) as a novel, potent, and selective agonist for group III mGluRs. In recombinant cell lines expressing the human receptors hmGluR4a, hmGl...
BACKGROUND The aim of the study was to analyse the toxicity and health related quality of life (HRQoL) of breast cancer patients treated with FAC (5-fluorouracil, doxorubicin, cyclophosphamide) and TAC (docetaxel, doxorubicin, cyclophosphamide) with and without primary prophylactic G-CSF (PPG). PATIENTS AND METHODS This was a phase III study to compare FAC and TAC as adjuvant treatment of hig...
Over 100 algorithms have been proposed to estimate respiratory rate (RR) from the electrocardiogram (ECG) and photoplethysmogram (PPG). As they have never been compared systematically it is unclear which algorithm performs the best. Our primary aim was to determine how closely algorithms agreed with a gold standard RR measure when operating under ideal conditions. Secondary aims were: (i) to co...
AIM To evaluate the pharmacodynamics of lixisenatide once daily vs sitagliptin once daily in Japanese patients with type 2 diabetes receiving insulin glargine U100. MATERIALS AND METHODS This multicentre, open-label, phase IV study (NEXTAGE Study; ClinicalTrials.gov number, NCT02200991) randomly assigned 136 patients to either lixisenatide once daily via subcutaneous injection (10 µg initiall...
The finding that liver necrosis caused by the environmental glutathione (GSH)-depleting chemical, bromobenzene (BB) is associated with marked impairment in O- and S-methylation of BB metabolites in Syrian hamsters raises questions concerning the role of methyl deficiency in BB toxicity. N-Acetylmethionine (NAM) has proven to be an effective antidote against BB toxicity when given after liver GS...
In this work, a model to estimate systolic blood pressure (SBP) using photoplethysmography (PPG) and electrocardiography (ECG) is proposed. Data from 19 subjects doing a 40 min exercise was analyzed. Reference SBP was measured at the finger based on the volume-clamp principle. PPG signals were measured at the finger and forehead. After an initialization process for each subject at rest, the mod...
OBJECTIVE To evaluate whether fat quality, in the context of meals with high- (HGI) or low-glycemic index (LGI), influences postprandial blood glucose (PPG) response in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS According to a randomized crossover design, 13 patients with type 1 diabetes on insulin pump consumed two series (HGI or LGI) of meals with the same carbohydrate quant...
فوتوپلتیسموگرام (PPG) یکی از کم‌هزینه‌ترین سیگنال‌ها است که همواره مورد توجه محققان به منظور استخراج پارامترهای سیستم قلبی-عروقی مانند میزان اتساع شریانی در پی تحریک بوده است. در اکثر موارد PPGاز نوک انگشت ثبت می‌شود که تحت تأثیر سیستم خودتنظیم عروقی است،...
