    In this study, we conducted molecular detection and characterization of piroplasms that infect the Ethiopian or desert hedgehogs (Paraechinus aethiopicus) in Saudi Arabia. Blood samples from 112 (68 males and 44 females) desert hedgehogs from Unaizah, Central Saudi Arabia were screened for Theileria/Babesia DNA using the polymerase chain reaction (PCR) employing specific primers amplifying the partial 18S small subunit rRNA gene. Theileria DNA was detected in 51 samples (45·5%), giving a prevalence of 45·5%. Theileria DNA was found in 33 (48·5%) males and 18 (40·9%) females, and there was no significant difference (P > 0·05) in the prevalence between males and females. Similarly, there was no significant difference (P > 0·05) in the prevalence between juveniles (40%) and adults (46·7%). There was a significant difference in the prevalence of Theileria in hedgehogs collected from May to September and the period from October to April (P = 0·003). Four haplotypes of Theileria sp. in hedgehogs were detected and designated as H1-H4. H1 was the predominant haplotype and found in 80·8% of the positive individuals. Partial sequences of the 18S rRNA of Theileria sp. from hedgehogs grouped with Theileria spp. that are benign. This study is the first report of the occurrence of Theileria spp. in Saudi Arabian desert hedgehogs.

    Orchids depend primarily on mycorrhizal fungi to obtain nutrients throughout their life cycle. Epiphytic orchids account for 69% of orchid diversity. The unstable availability of water and nutrients in their arboreal habitats often results in severe water and nutrient stresses. Consequently, mycorrhizal associations may be important for the survival of epiphytic orchids, but our understanding thereof remains limited. Here, we investigated the mycorrhizal community in a single epiphytic orchid species, using more samples than in any previous study.

    We assessed the mycorrhizal communities of Thrixspermum japonicum, one of the most common epiphytic orchids in the temperate region of Japan. In total, 144 individuals were collected from 28 host tree species at 20 sites across 1300km. The mycorrhizal fungi were identified based on nuclear ribosomal DNA internal transcribed spacer sequences and assigned operational taxonomic units (OTUs) based on 97% sequence similarity.

    We obtained 24 OTUs; 9 belonged to the Ceratobasidiaceae and 15 to the Tulasnellaceae. These OTUs are widely distributed throughout the phylogenetic trees of the two fungal families. However, a single Ceratobasidiaceae OTU accounted for 49.7% of all fungal sequences and was predominant in samples from 15 host tree species and 12 sites.

    Our results imply that despite having a broad range of mycorrhizal partners, T. japonicum was predominantly associated with a single fungal taxon at most of the sites among the host-tree species investigated. These findings contribute to elucidating mycorrhizal symbiosis in epiphytic habitats.

    This study was aimed at assessing the possible effect of melatonin concentration on migraine. The serum concentration profile of melatonin in patients with diagnosed episodic migraine in the interictal period was compared to the profile in patients without migraine. see more Then, a correlation between the frequency and duration of migraine attacks, and the possible relationship between these parameters and melatonin levels in individual patients, was established.

    Melatonin secretion is related to migraine pathophysiology in many different ways.

    The study was conducted in a group of 58 subjects (48 women and 10 men). The study group comprised 29 patients (24 women and five men) diagnosed with migraine according to the International Classification of Headache Disorders (ICHD-3 beta), within the framework of the Outpatient Clinic at Bielanski Hospital in Warsaw and the Clinical Department of Neurology of the 2nd Faculty of Medicine (now known as the Faculty of Medical Sciences) at the Medical University of Warsaw,ctal period. The results of studies available in the literature depend on the nature of the headache (episodic or chronic) and the time of measuring the concentration of melatonin (during a headache attack or in an interictal period).

    Our study showed no abnormalities of melatonin secretion in patients with migraine during the interictal period. The results of studies available in the literature depend on the nature of the headache (episodic or chronic) and the time of measuring the concentration of melatonin (during a headache attack or in an interictal period).

    Migraine attacks notably impact people’s daily lives, health-related quality of life (HRQoL), and ability to work. Triptans are widely used as acute medication for a migraine attack but are ineffective, poorly tolerated, or contraindicated in some patients. HRQoL and work productivity are therefore likely to pose particular problems for patients whose migraine attacks do not respond sufficiently to triptan acute treatment. This real-world study aimed to determine whether migraine-related HRQoL, disability, and work productivity differed between triptan insufficient responders (TIRs) and sufficient responders (TSRs) receiving this acute treatment for migraine in Japan.

    This was a retrospective analysis of 2017 Adelphi Migraine Disease Specific Programme cross-sectional survey data collected from physicians and their consulting patients with migraine in Japan. Patients had to be receiving a triptan as their sole acute prescribed medication for migraine. TIRs were defined as patients who achieved headache pare effective acute treatment options.

    Migraine attacks had a negative impact on the HRQoL, disability, and work productivity of people with migraine in Japan reporting insufficient efficacy with acute triptan treatment, highlighting the need for more effective acute treatment options.
