Light, fluorescence, and electron microscopy were applied to cross sections and -breakage and whole-mount preparations of the anterior hindwing vein of the shield bug Graphosoma italicum. These analyses were complemented by investigations of the basal part of the forewing Corium and Clavus. The integration of structural, histological, and fluorescence data revealed a complex arrangement of both rigid and elastic structures in the wall of wing veins and provided insights into the constitution of transition zones between rigid and elastic regions.

Background: Having a poor teat-end condition is associated with increased mastitis risk, hence avoiding milking machine settings that have a negative effect on teat-end condition is important for successful dairy production. Milking-time testing (MTT) can be used in the evaluation of vacuum conditions during milking, but the method is less suited for herds using automatic milking systems (AMS) and relationships with teat end condition is poorly described. This study aimed to increase knowledge on interpretation of MTT in AMS and to assess whether milk-flow data obtained routinely by an AMS can be useful for the management of teat-end health.

Ageing process is associated with changes to the aspect, biomechanics, structure and function of the foot, it may be related with a marked presence of foot conditions, pain, disability and other overall health problems that constitute a major public health concern. Also, the prevalence of epidemiologic research found an incidence of foot problems which is even higher as a consequence of increasing life expectation. Several studies have also suggested that such foot disorders currently affect between 71 and 87% of older patients and are a frequent cause of medical and foot care. Read More

Background: We aimed to compare the postoperative height of the second metatarsal head relative to the first metatarsal head using axial radiographs among 3 different commonly used osteotomy techniques: proximal chevron metatarsal osteotomy (PCMO), scarf osteotomy, and distal chevron metatarsal osteotomy (DCMO).

Methods: We retrospectively reviewed the radiographs and clinical findings of the patients with painful callosities under the second metatarsal head, complicated by hallux valgus, who underwent isolated PCMO, scarf osteotomy, or DCMO from February 2005 to January 2015. Each osteotomy was performed with 20 degrees of plantar ward obliquity. Read More

Popcorn is widely consumed in Brazil, yet there are few breeding programs for this crop. Recurrent selection (RS) is a viable breeding alternative for popcorn; however, the gains achieved must be frequently checked. The aim of this study was to assess the effect of selection for grain type (round and pointed) after four cycles of phenotypic RS on the main agronomic traits of popcorn, to estimate the genetic gain achieved for the trait of expansion volume (EV), and to obtain estimates of phenotypic correlations for the main traits of the crop in the UFLA E and UFLA R populations.

Objectives: To determine whether preoperative pain intensity in callosities of the lesser toe metatarsopharangeal (MTP) joint was associated with the grade of fore-mid-hindfoot deformities, because rheumatoid arthritis (RA) foot deformity includes the whole part of foot, and curiously differences between cases in the pain intensity of MTP joint callosities are often observed.

Methods: We evaluated 24 feet that had undergone forefoot surgery [August, 2014 - December, 2015] for painful lesser toe MTP joint deformity (callosities) in RA cases. A preoperative self-administered foot evaluation questionnaire (SAFE-Q) and pressure distribution information for foot function were also investigated. Read More

This study assesses the effect of salicylic acid plasters on the time to resolution of 324 corns experienced by 201 participants taking part in a randomized controlled trial. While the rate of corn resolution was substantively higher in the treatment group than in the control group, treatment was found to be not significantly related to time to corn recurrence when analyzed over the full 12-month follow-up period. Parametric survival analysis modeling of interval-censored data and incorporating patient-specific frailty terms was utilized, to model correlation of corns within patients (hazard ratio [HR], 1.

Pachyonychia congenita (PC) is a rare genodermatosis caused by a mutation in keratin genes, which can lead to hypertrophic nail dystrophy and focal palmoplantar keratoderma (predominantly plantar), amongst other manifestations. Painful blisters and callosities, sometimes exacerbated by hyperhidrosis, are major issues that can have a significant impact on patient quality of life. Many alternative treatments for this condition have been applied with variable and partial clinical response, but a definitive cure for this disease has yet to be discovered. Read More

Introduction: This case report will have implications for any area of medicine that aims to redistribute plantar pressure away from a particular area of the foot. This could be for example in the short-term care of people with diabetes, people who have insensate feet and people with poor blood supply to the foot coupled with plantar ulceration. The aim of the study was to investigate which type and thickness of Hapla felt padding is the most effective at redistributing plantar pressure of the foot. Read More

Objective: Foot deformities, neuropathy, and dysfunction in the lower extremities are known risk factors that increase plantar peak pressure (PP) and, as a result, the risk of developing foot ulcers in patients with diabetes. However, knowledge about the prevalence of these factors is still limited. The aim of the present study was to describe the prevalence of risk factors observed in patients with diabetes without foot ulcers and to explore possible connections between the risk factors and high plantar pressure.
