Patients with alien hand (AH) syndrome from medial frontal lesions exhibit involuntary but seemingly purposeful contralesional upper limb movements. Two observations about AH patients have received little, if any, experimental confirmation. The first is that AH is triggered opportunistically by nearby objects. The second is that AH behaviors are increased in conditions of fatigue or anxiety, i....

OBJECTIVE Platelet-activating factor acetylhydrolase (PAF-AH) expresses a Ca2+-independent phospholipase A2 activity and hydrolyzes platelet-activating factor as well as oxidized phospholipids. Two major types of PAF-AH have been described: the plasma type, which is associated with lipoproteins, and the intracellular type II PAF-AH. METHODS AND RESULTS We investigated the type(s) of PAF-AH ex...

l,rAzobis[3-methyl-2-phenyl-lH-imidazo(l,2-a)pyridinium] dibromide, AH 8165, produced a competitive neuromuscular block in the mouse, chick, cat, dog and monkey. The paralysis was characterized by a very rapid onset of action and, in all species except the monkey, by a short duration of action comparable to that of suxamethonium. In the monkey, the effect of AH 8165 was more persistent but was ...

One-hundred ninety-two crossbred steers (initial BW = 351 +/- 11 kg) were used to determine the effects of removing alfalfa hay (AH) from dry-rolled corn-based diets containing wet corn gluten feed (WCGF) on animal performance and nutrient (N and OM) mass balance in open feedlot pens. Steers were stratified by weight and assigned randomly to 24 pens (2 x 3 factorial) and fed for 132 d from June...

INTRODUCTION Assessment of cellular cytotoxicity is a regular method for evaluating the biocompatibility of novel materials. In a recent study, 5% fluoride varnish (Duraflur) has shown reasonable sealing ability and coverage of root canal walls when used as a sealer. The aim of the present study was to compare the cytotoxicity of Duraflur varnish with two popular commonly used root canal sealer...

Our aim was to find out if immunoglobulins for intravenous use (IVIG) contain IgG-anti-F(ab')2γ (AFab2) and IgG-antiHinge (AH) antibodies (Ab.) and to discuss how AFab2, in particular AH could contribute to immunomodulatory effect of IVIGs. We measured IgG, AFab2 and AH in five IVIG products approved for therapeutic use. IVIG showed higher AFab2 and AH concentration than sera of randomized heal...

OBJECTIVE In search of an ideal method of assisted hatching (AH), we compared the effects of conventional micropipette-AH and laser-AH on the blastocyst formation rate (BFR) and blastocyst cell numbers. METHODS Four- to five-week-old ICR female mice were paired with male mice after superovulation using Pregnant mare's serum gonadotropin (PMSG) and hCG. The two-cell embryos were flushed from t...

BACKGROUND Water extract from the root of Allium hookeri (AH) shows anti-inflammatory, antioxidant, and free radical scavenging effects. In this study, the ameliorating effects of AH on oxidative stress-induced inflammatory response and β-cell damage in the pancreas of streptozotocin (STZ)-induced type 1 diabetic rats were investigated. METHODS AH (100 mg/kg body weight/day) was orally admini...

The treatment of primary vitreoretinal lymphoma (PVRL) remains controversial regarding the use local, systemic, or combined treatments. aim this study was to analyze efficacy and toxicity intravenous high-dose methotrexate (IV HD-MTX) based systemic therapy in a uniformly treated population PVRL patients. From nationwide French database, we retrospectively selected 59 patients (median age: 70 y...

STUDY OBJECTIVE Hysterectomy for presumed leiomyomata is 1 of the most common surgical procedures performed in nonpregnant women in the United States. Laparoscopic hysterectomy (LH) with morcellation is an appealing alternative to abdominal hysterectomy (AH) but may result in dissemination of malignant cells and worse outcomes in the setting of an occult leiomyosarcoma (LMS). We sought to evalu...
