Anatomy and connectivity of the Göttingen minipig subgenual cortex (Brodmann area 25 homologue).

Background: The subgenual gyrus is a promising target for deep brain stimulation (DBS) against depression. However, to optimize this treatment modality, we need translational animal models.

Aim: To describe the anatomy and connectivity of the Göttingen minipig subgenual area (sgC).

Cryoneurolysis versus radiofrequency ablation outcome on pain experience in chronic low back pain (COPE): a single-blinded randomised controlled trial.

Objective: A comparison of cryoneurolysis or radio frequency (RF) with placebo in patients with facetogenic chronic low back pain (LBP) for patient global impression of change (PGIC), pain intensity, function and quality of life, with 1-year follow-up.

Design: Single-centre, single-blinded placebo-controlled randomised controlled trial.

Setting: Single-centre study.

Spontaneous partial recovery of striatal dopaminergic uptake despite nigral cell loss in asymptomatic MPTP-lesioned female minipigs.

The Göttingen minipig is a large animal with a gyrencephalic brain that expresses -complex behavior, making it an attractive model for Parkinson's disease research. Here, we investigate the temporal evolution of presynaptic dopaminergic function for 14 months after injections of 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) into the minipig using a multi-tracer longitudinal positron emission tomography (PET) design. We injected seven sedated minipigs with 1-2 mg/kg of MPTP, and two with saline, three times a week over four weeks.

Non-ablative doses of focal ionizing radiation alters function of central neural circuits.

Background: Modulation of pathological neural circuit activity in the brain with a minimum of complications is an area of intense interest.

Objective: The goal of the study was to alter neurons' physiological states without apparent damage of cellular integrity using stereotactic radiosurgery (SRS).

Methods: We treated a 7.

Anatomy and histology of the Göttingen minipig adenohypophysis with special emphasis on the polypeptide hormones: GH, PRL, and ACTH.

The pituitary is involved in the regulation of endocrine homeostasis. Therefore, animal models of pituitary disease based on a thorough knowledge of pituitary anatomy are of great importance. Accordingly, we aimed to perform a qualitative and quantitative description of polypeptide hormone secreting cellular components of the Göttingen minipig adenohypophysis using immunohistochemistry and stereology.

An Intracortical Implantable Brain-Computer Interface for Telemetric Real-Time Recording and Manipulation of Neuronal Circuits for Closed-Loop Intervention.

Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces (BCIs) should ideally operate un-tethered and allow chronic longitudinal manipulations in the freely moving animal. In this study, we designed a new intracortical BCI feasible of telemetric recording and stimulating local gray and white matter of visual neural circuit after irradiation exposure.

A Perspective of International Collaboration Through Web-Based Telecommunication-Inspired by COVID-19 Crisis.

The tsunami effect of the COVID-19 pandemic is affecting many aspects of scientific activities. Multidisciplinary experimental studies with international collaborators are hindered by the closing of the national borders, logistic issues due to lockdown, quarantine restrictions, and social distancing requirements. The full impact of this crisis on science is not clear yet, but the above-mentioned issues have most certainly restrained academic research activities.

Towards a Göttingen minipig model of adult onset growth hormone deficiency: evaluation of stereotactic electrocoagulation method.

Background: Adult onset growth hormone (GH) deficiency (AGDH) is a potentially underdiagnosed condition, caused by damage to the pituitary gland. AGHD is treated with growth hormone replacement therapy. A large variety of clinical symptoms and changes in the metabolic homeostasis can be observed and quantified.

Age as a prognostic factor in relation to surgical evacuation of spontaneous supratentorial intracerebral haemorrhage.

Aim And Clinical Rationale For The Study: Spontaneous intracerebral haemorrhage (sICH) is an acute life-threatening injury and constitutes 10-15% of first-ever stroke cases. The Surgical Trials in Intracerebral Haematoma studies (STICH and STICH II) represent the two foremost studies in the field, however, with arguable shortcomings. To find more accurate criteria, we aimed to correlate the preoperative neurological and neuroimaging findings with the clinical outcome of operated patients.

Effect of spinal anterior root stimulation and sacral deafferentation on bladder and sexual dysfunction in spinal cord injury.

Background: Spinal cord injury (SCI) is a highly devastating injury with a variety of complications; among them are neurogenic bladder, bowel, and sexual dysfunction. We aimed to evaluate the effect of sacral anterior root stimulation with sacral deafferentation (SARS-SDAF) on neurogenic bladder and sexual dysfunction in a large well-defined spinal cord injury cohort.

Methods: In the manner of cross-sectional study, subjects undergone SARS-SDAF between September 1986 and July 2011 answered a questionnaire concerning conditions before and after surgery in the department of Neuro-Urology, Bad Wildungen, Germany.

Nigrostriatal proteasome inhibition impairs dopamine neurotransmission and motor function in minipigs.

Parkinson's disease (PD) is characterized by degeneration of dopaminergic neurons in the substantia nigra leading to slowness and stiffness of limb movement with rest tremor. Using ubiquitin proteasome system inhibitors, rodent models have shown nigrostriatal degeneration and motor impairment. We translated this model to the Göttingen minipig by administering lactacystin into the medial forebrain bundle (MFB).
