Metallic trace elements in marine sponges living in a semi-enclosed tropical lagoon.

The ability of marine filter feeders to accumulate metals could help monitor the health of the marine environment. This study examined the concentration of metallic trace elements (MTE) in two marine sponges, Rhabdastrella globostellata and Hyrtios erectus, from three sampling zones of the semi-enclosed Bouraké Lagoon (New Caledonia, South West Pacific). MTE in sponge tissues, seawater, and surrounding sediments was measured using inductively coupled plasma with optical emission spectroscopy.

Coexistence of neuropathic corneal pain, corneal nerve abnormalities, depression, and low quality of life.

Purpose: To evaluate the quality of life (QoL), mental health conditions and corneal morphology in neuropathic corneal pain (NCP) subjects without a significant ocular surface disease.

Methods: A composite questionnaire was administered to 228 consecutive subjects, assessing the pain intensity, duration, and quality using a modified version of the Self-Administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) and Pain Detect (PD) questionnaires. Subjects diagnosed with possible central NCP and two sub-groups of patients diagnosed with peripheral ocular pain completed an additional battery of mental health questionnaires and were examined by In Vivo Confocal Microscopy (IVCM).

Sponge organic matter recycling: Reduced detritus production under extreme environmental conditions.

Sponges are a key component of coral reef ecosystems and play an important role in carbon and nutrient cycles. Many sponges are known to consume dissolved organic carbon and transform this into detritus, which moves through detrital food chains and eventually to higher trophic levels via what is known as the sponge loop. Despite the importance of this loop, little is known about how these cycles will be impacted by future environmental conditions.

Efficacy of a long-term acting triptan for Headache attributed to aeroplane travel: a case report.

Headache attributed to aeroplane travel (AH) is a well-defined nosological entity whose diagnostic criteria have been published in the third provisional International Classification of Headache Disorders (ICHD) and confirmed in the definitive version. Despite the severe intensity of pain, less than half of the AH cases described used medications for preventing the attack. The most frequent prophylactic therapy spontaneously used by sufferers are simple analgesics, non-steroidal anti-inflammatory drugs (NSAIDs), and nasal decongestants, achieving a complete or partial benefit in about 50% of patients.

The relevance of migraine in the clinical spectrum of mitochondrial disorders.

Recent scientific evidence suggests a link between migraine and brain energy metabolism. In fact, migraine is frequently observed in mitochondrial disorders. We studied 46 patients affected by mitochondrial disorders, through a headache-focused semi-structured interview, to evaluate the prevalence of migraine among patients affected by mitochondrial disorders, the possible correlations between migraine and neuromuscular genotype or phenotype, comorbidities, lactate acid levels and brain magnetic resonance spectroscopy.
