BACKGROUND To evaluate the effects of nurse-led multifactorial care to prevent disability in community-living older people. METHODS In a cluster randomized trail, 11 practices (n = 1,209 participants) were randomized to the intervention group, and 13 practices (n = 1,074 participants) were randomized to the control group. Participants aged ≥ 70 years were at increased risk of functional decli...

Objective: The study was aimed to elucidate risk factors identifiable from ward-derived data of thirty-day re-hospitalization among patients undergoing total hip and knee arthroplasty.
 Methods: designed as a cross-sectional prospective study. the were collected through Patient Sociodemographic Form, Nurse Physical Assessment Observation Charlson Comorbidity Index (CCI), Katz Activities Da...

BACKGROUND Kato-Katz is a widely used method for the diagnosis of soil-transmitted helminth infection. Fecal samples cannot be preserved, and hence, should be processed on the day of collection and examined under a microscope within 60 min of slide preparation. Mini-FLOTAC is a technique that allows examining fixed fecal samples. We assessed the performance of Mini-FLOTAC using formalin-fixed s...

BACKGROUND Emergence of human fascioliasis prompted a worldwide control initiative including a pilot study in a few countries. Two hyperendemic areas were chosen: Huacullani, Northern Altiplano, Bolivia, representing the Altiplanic transmission pattern with high prevalences and intensities; Cajamarca valley, Peru, representing the valley pattern with high prevalences but low intensities. Coprol...

Memory and dementia are historical ideas that preceded the development of modern neuroscientific, psychogeriatric and medical approaches to aging and cognitive impairment. This article explores the value of such historical ideas in order to understand the discourses and metaphors by which Western thought has individualized memory as the guarantor of rational personhood, while at the same, treat...

It is generally believed (1-3) that T lymphocytes recognize antigen in association with products of the major histocompatibility complex (MHC).I If we consider T cell responsiveness in terms of a recognition unit, it would be made up of three components: antigen, a T cell receptor (s), and a surface Ia molecule on an antigenpresenting cell (APC). In such a model, lack of responsiveness (Ir gene...

We show that any two-dimensional odd dihedral representation ρ over a finite field of characteristic p > 0 of the absolute Galois group of the rational numbers can be obtained from a Katz modular form of level N , character 2 and weight k, where N is the conductor, 2 is the prime-to-p part of the determinant and k is the so-called minimal weight of ρ. In particular, k = 1 if and only if ρ is un...

A conjecture connected with quantum physics led N. Katz to discover some amazing mixed character sum identities over a field of q elements, where q is a power of a prime p > 3. His proof required deep algebro-geometric techniques, and he expressed interest in finding a more straightforward direct proof. The first author recently gave such a proof of his identities when q ≡ 1 (mod 4), and this p...

(a) Fix an encryption scheme Π for messages of length `(n) and an adversaryA, and consider the following experiment BWA,Π(n): i. A random key k ← {0, 1}n and message m ← {0, 1}`(n) are chosen. ii. A is given the ciphertext C ← Enck(m). iii. A outputs a pair (i, b), with i ∈ {1, . . . , `(n)} and b ∈ {0, 1}. The output of the experiment is 1 iff b = mi, where mi denotes the ith bit of m. We say ...

True science recognizes no boundaries and it is best exemplified by the life of Sir Bernard Katz, an ideal role model for a generation of physiologists and pharmacologists and who was instrumental in the " Quantum " jump in the knowledge of synaptic physiology. Germany on 26th March 1911. As a child till 6 years, Bernard Katz was a citizen of Russia but became stateless because of the Russian R...
