Balance and gait disorders in de novo Parkinson's disease: support for early rehabilitation.

Background: Postural instability is considered a late complication of Parkinson's disease (PD). However, growing evidence shows that balance and gait problems may occur early in the disease.

Objective: To describe balance, gait, and falls/near falls in persons with newly diagnosed, untreated PD ("de novo"), and to compare this with persons with mild-moderate PD (Later PD).

Small cells with big photosynthetic productivities: biotechnological potential of the Picochlorum genus.

The Picochlorum genus is a distinctive eukaryotic green-algal clade that is the focus of several current biotechnological studies. It is capable of extremely rapid growth rates and has exceptional tolerances to high salinity, intense light, and elevated temperatures. Importantly, it has robust stability and high-biomass productivities in outdoor field trials in seawater.

Development and evaluation of a standardised sampling protocol to determine the effect of cleaning in the pig sty.

Background: All-in, all-out with strict hygienic routines is necessary in modern pig production. Furthermore, a standardised, validated method is needed to quantitatively control the effect of these hygiene protocols. This study aimed to establish a reproducible and reliable sampling method to assess cleaning of the pig pen.

Cyanobacteria newly isolated from marine volcanic seeps display rapid sinking and robust, high-density growth.

Unlabelled: Cyanobacteria are photosynthetic organisms that play important roles in carbon cycling and are promising bioproduction chassis. Here, we isolate two novel cyanobacteria with 4.6Mbp genomes, UTEX 3221 and UTEX 3222, from a unique marine environment with naturally elevated CO₂.

Assessment of intraepidermal nerve fiber densities in 5 µm sections from arm and leg - a search for normative age-related values.

Normative values are lacking regarding intraepidermal nerve fiber density (IENFD) in thin sections of 5 µm. Thus, we aimed to assess IENFD in thin sections in a healthy adult population as well as to investigate whether IENFD is related to age, sex, and site of excision. Archival skin biopsies or excisions at the Department of Pathology, Lund, Sweden, from arm and leg were collected, re-sectioned, and immunohistochemically stained for Protein Gene Product 9.
