During the last five years, several research review studies have revealed insufficient or even no proof that courses in manual material handling (MMH) are effective at preventing musculoskeletal disorders (MSD). These revelations are placing the current daily practice of MMH trainers under scrutiny. This study analyses how the MMH courses are organised in practice. A web-based questionnaire was...

The interaction of methylmercury hydroxide (MMH) and cholinesterases was studied in male and female rats. MMH administered subcutaneously in doses of 10 mg/kg for 2 days reduced the level of plasma cholinesterase (ButChE) by 68% in females and 47% in males while brain acetylcholinesterase (AChE) was unaffected. Normal females had higher but more variable ButChE levels than normal males. In a ti...

To compare the efficacy of homemade anal cushion suspension clamp combined with harmonic scalpel (ACS) and Milligan-Morgan hemorrhoidectomy combined with electric knife (MMH) in the treatment of stages III to IV hemorrhoids. We conducted a retrospective study of 99 patients with stages III to IV hemorrhoids hospitalized from January to December in 2013. Among them, 51 patients were treated with...

347 Ruth Zu-Kei Lin, RN, MSN, AOCN®, APN-C, is an oncology clinical nurse specialist at Morristown Memorial Hospital (MMH) in New Jersey; Susan Fowler, PhD, RN, CNRN, FAHA, is a clinical nurse researcher at the Visiting Nurse Association of Central Jersey in Red Bank and was a clinical nurse researcher at MMH at the time of this research; and Craig A. Dise, MD, PhD, is chair of pathology and Ra...

The major mutagenic base lesion in DNA caused by exposure to reactive oxygen species is 8-hydroxyguanine or 7, 8-dihydro-8-oxoguanine (8-OH-G). Products of the human MMH/OGG1 gene are known to catalyze in vitro the reactions repairing this DNA lesion. To analyze the function of Mmh in vivo, we generated a mouse line carrying a mutant Mmh allele by targeted gene disruption. Mmh homozygous mutant...

Previous research has suggested that adolescents with myelomeningocele and shunted hydrocephalus (MMH) have difficulties with aspects of executive functioning and, in turn, with functional independence. There is little research, however, examining patterns of executive functioning across adolescence in this population. The goal of this cross-sectional study was to examine parent ratings of exec...

Hepatitis A virus (HAV) has been adapted to grow efficiently in primate and some nonprimate cell lines but not in cells of murine origin. To understand the inability of the virus to grow in mouse cells, we studied the replication of HAV in immortalized and nontransformed MMH-D3 mouse liver cells, which require growth factors and collagen to maintain their phenotype. HAV grew in MMH-D3 cells tra...

Manual material handling (MMH) tasks can be found in most workplaces and they may constitute a risk factor for work-related musculoskeletal disorders (WMSDs). This study was conducted to determine the prevalence of WMSDs and to compare MMH loads with the acceptable weight and force limits among Iranian casting workers. Data were collected from 50 workers of casting workshops who performed MMH t...

Studies were conducted to define the specific changes in the urinary porphyrin excretion pattern (porphyrin profile) and the time course of those changes in rats exposed to mercury as methyl mercury hydroxide (MMH) at 5 or 10 ppm in the drinking water for up to 30 weeks. The urinary porphyrin profile elicited by MMH is uniquely characterized by highly elevated levels of 4- and 5-carboxyl porphy...

Maternal mental health (MMH) problems are associated with lack of confidence in one's parenting, overly lax or too harsh discipline, and child academic underperformance. We asked if parenting mediates the effect of MMH problems on academic outcomes even among mothers with serious mental illness (n=164). Structural equation analyses show a significant association between MMH problems and permiss...
