In mammalian genomes a sixth base, 5-hydroxymethylcytosine ((hm)C), is generated by enzymatic oxidation of 5-methylcytosine ((m)C). This discovery has raised fundamental questions about the functional relevance of (hm)C in mammalian genomes. Due to their very similar chemical structure, discrimination of the rare (hm)C against the far more abundant (m)C is technically challenging and to date no...

In this paper, we present an efficient cryptanalysis of the socalled HM cryptosystem which was published at Asiacrypt’1999, and one perturbed version of HM. Until now, this scheme was exempt from cryptanalysis. We first present a distinguisher which uses a differential property of the public key. This distinguisher permits to break one perturbed version of HM. After that, we describe a practica...

Herbal medicine (HM) is one of the most widely used Complementary and Alternative Medicine (CAM) therapies throughout the world. The WHO has recognized HM as an essential component of primary healthcare. The aim of this study was to explore patients' attitudes towards using HM, their sources of information and the role of costs. Within a qualitative research approach, semi-standardized intervie...

OBJECTIVES Patients with systemic lupus erythematosus (SLE) are at higher risk of haematological malignancies (HMs) than the general population. Most reports have focused on HM diagnosed after SLE, and have excluded concurrent and preceding diagnoses. Information on response to therapy is also limited. METHODS We identified 13 296 cases of HM and 10 539 potential patients with SLE at our cent...

Determination of K-value (fish freshness index) and histamine (Hm) of mackerel and tuna during storage at various temperatures was done by using the oxygen-sensor method. Hm in mackerel increased even at low temperature (5 degrees C), and reached the Defect Action Level (DAL) of the U.S. FDA, 5 mg/100 g, before the K-value approached the inedible level. As the storage temperature was increased,...

BACKGROUND Although 98% of mothers in our cohort initiated human milk (HM) provision for their very low-birthweight (VLBW) infants, fewer black infants received HM at neonatal intensive care unit (NICU) discharge than non-black infants. This study examined neighborhood structural factors associated with HM feeding at discharge to identify potential barriers. MATERIALS AND METHODS Sociodemogra...

We present a systematic review of existing research that aims to assess the efficacy and safety of herbal medications (HM), as either monotherapy or adjunct to orthodox medications (OM), mainly comprised of cholinesterase inhibitors, for vascular dementia (VaD). We included 47 studies conducted in mainland China, each testing different HM. Of 43 HM monotherapy studies, 37 reported HM to be sign...

Background: The sporadic type of Hemiplegic Migraine (HM) is sometimes observed among migrainous patients (MP) and mimics ischemic strokes. Methods: In an evaluation of two-hundred consecutive adult MP in the Mackenzie headache clinic, Canada during 2004 , 9% of the patients met the criteria established by the International Headache Society for sporadic HM. Female to male sex ratio, family...

Excessive heavy metals (HMs) in agricultural lands cause toxicities to plants, resulting in declines in crop productivity. Recent advances in ethylene biology research have established that ethylene is not only responsible for many important physiological activities in plants but also plays a pivotal role in HM stress tolerance. The manipulation of ethylene in plants to cope with HM stress thro...
