Listeria monocytogenes is a pathogen frequently associated with ready-to-eat (RTE) meat and poultry products. Nitrite is a key antimicrobial additive that can offer some degree of protection against L. monocytogenes when included in meat product formulations.

Objective: Non-traumatic lower limb amputation (NT-LLA) has consequences at individual and public health levels. Population based studies in sub-Saharan Africa are scarce and often related to single centre series. This study aimed to estimate the incidence of NT-LLA (minor and major) and to describe epidemiological, clinical, and prognostic aspects in Togo.

Breeding for variation in photoperiod response is crucial to adapt crop plants to various environments. Plants measure changes in day length by the circadian clock, an endogenous timekeeper that allows plants to anticipate changes in diurnal and seasonal light-dark cycles. Here, we describe the early maturity 7 (eam7) locus in barley (Hordeum vulgare), which interacts with PHOTOPERIOD 1 (Ppd-H1) to cause early flowering under non-inductive short days.

In biological sciences, DNA fingerprinting has been widely used for paternity testing, forensic applications and phylogenetic studies. Here, we describe a reliable and robust method for genotyping individuals by Variable Number of Tandem Repeat (VNTR) analysis in the context of undergraduate laboratory classes. The human D1S80 VNTR locus is used in this protocol as a highly polymorphic marker based on variation in the number of repetitive sequences.

Inflorescence architecture dictates the number of flowers and, ultimately, seeds. The architectural discrepancies between two related cereals, barley and wheat, are controlled by differences in determinacy of inflorescence and spikelet meristems. Here, we characterize two allelic series of mutations named () and () that convert barley indeterminate inflorescences into wheat-like determinate inflorescences bearing a multifloreted terminal spikelet and spikelets with additional florets.

The modification of shoot architecture and increased investment into reproductive structures is key for crop improvement and is achieved through coordinated changes in the development and determinacy of different shoot meristems. A fundamental question is how the development of different shoot meristems is genetically coordinated to optimize the balance between vegetative and reproductive organs. Here we identify the () gene as a major regulator of plant architecture in barley ().

The posterolateral hip approach is the oldest and most used way to implant total hip arthroplasty. The anterior part of the oblique portion of this posterolateral approach corresponds more or less to the superolateral quadrant of the buttock in which the intramuscular injection of various drugs, including the compounds derived from artemisinin, is carried out. Thus, in a malarial endemic area where gluteal injections of the compounds derived from artemisinin are not rare, poor performance of an injection by the deposition of the product in the fat and not deeply in the muscle can be at the origin of the sequestration of the drug in adipose tissue and give the macroscopic appearance of a pus.

Introduction: The literature review revealed that nowadays only about 15 cases of bilateral shoulder dislocation associated with the fracture of the upper end of the humerus have been published. The triad of lesional mechanism designated by the triple syndrome E composed of epilepsy, electrocution, and external trauma was the circumstances noted in which these fractures dislocations occur with migration of the two humeral heads either forward or backward.

Case Report: An architect of 36-year-old, right-handed, was admitted in emergency department for loss of knowledge of progressive installation.

The purpose of this study was to describe the epidemiological and bacterial aspects of chronic osteomyelitis at the regional hospital of Tenkodogo, in Burkina Faso. This prospective study took place at the regional hospital in Tenkodogo during the 3 year-period 2011-2013 and included all cases of chronic osteomyelitis diagnosed during those years. The diagnosis was based on clinical and radiological evidence.

Introduction: The use of Masquelet technique is a serious option to consider for biologic reconstruction of severe bone loss. Here is exposed a continuous and prospective study on bone loss management using that technique. The aims of this study were to assess epidemiology of bone loss due either to trauma or to non-unions and to give preliminary results.

The complex nature of crop genomes has long prohibited the efficient isolation of agronomically relevant genes. However, recent advances in next-generation sequencing technologies provide new ways to accelerate fine-mapping and gene isolation in crops. We used RNA sequencing of allelic () mutants with altered spikelet development for gene identification and functional analysis in barley ().

Background: Nigeria was one of 3 polio-endemic countries before it was de-listed in September 2015 by the World Health Organization, following interruption of transmission of the poliovirus. During 2011-2014, Nigeria conducted serial polio seroprevalence surveys (SPS) in Kano Metropolitan Area, comprising 8 local government areas (LGAs) in Kano that is considered very high risk (VHR) for polio, to monitor performance of the polio eradication program and guide the program in the adoption of innovative strategies.

Methods: Study subjects who resided in any of the 8 local government areas of Kano Metropolitan Area and satisfied age criteria were recruited from patients at Murtala Mohammed Specialist Hospital (Kano) for 3 seroprevalence surveys.

Subacute subdural hematomas are a poorly individualized nosological entity, often equated clinically to chronic subdural hematomas. Yet, their neurological deterioration which is usually rapid seems to distinguish them from chronic subdural hematomas. We wanted to show this dangerousness by establishing the clinically evolving profile of the three types of subdural hematomas.

This study aimed at assessing the effectiveness of open reduction and plate fixation combined with autogenous bone grafting in the treatment of non-united fractures of the humeral shaft. Forty six patients (27 men, 19 women; mean age, 35.6 years; range, 23-53 years) were operated on for non-union of a diaphyseal fracture of the humerus.

Article Synopsis
  • The study aimed to identify risk factors for surgical wound infections in HIV-positive patients undergoing orthopedic surgery, analyzing the data from 36 patients aged 18 to 47 years.
  • Results showed that 39% of patients developed infections, primarily associated with their HIV clinical category and CD4+ lymphocyte levels, highlighting significant factors like contaminated wounds.
  • The findings suggest that recognizing these risk factors can help reduce complications and improve health outcomes for HIV-positive individuals undergoing surgery.
