In this study, we aimed to clarify the taxonomic status of Belonidae species distributed in the Mediterranean Sea and the Black Sea by conducting detailed genetic and morphological markers. A total of 550 needlefish samples were caught between January 2022 and January 2024. The data set used in the study contains a total of 171 sequences for the COI gene and 120 sequences for the 12s rRNA gene from different Belonidae species, including data from GenBank. Systematic analysis of needlefish species was investigated by using sequencing of mtDNA COI and 12s rRNA gene regions and morphological characters in the Turkish Marine Waters. A separate analysis of the two mitochondrial genes supported by morphological characters revealed that each species is grouped within itself. The genetic and morphological analyses showed that Belone belone acus and Belone belone euxini which are considered as the subspecies of Belone belone are not subspecies of the genus Belone and should be considered at the species level, Belone belone. Belone svetovidovi is also considerably different from Belone belone and should be considered as a different species. T. acus imperialis, which is thought to be distributed in the Mediterranean Sea, is not a subspecies of Tylosorus acus and should be revised as Tylosorus imperialis which genetically differs from Tylosorus acus and also other Tylosorus species at the species level.

Article Synopsis
- Patients with leprosy can experience acute inflammatory episodes called erythema nodosum leprosum (ENL), which involve painful skin nodules and systemic symptoms; neutrophils are believed to contribute to these episodes.
- A study compared transcriptomic data from the blood of patients with non-reactional lepromatous leprosy and those experiencing ENL, revealing that ENL patients exhibited a heightened expression of neutrophil activation and pro-inflammatory genes.
- Validation of the findings showed that the level of the neutrophil activation marker CD177 could differentiate between ENL and non-reactional cases, and higher CD177 levels were associated with more severe ENL episodes, suggesting its potential as a marker for EN
Macrophage immunophenotypes in Jorge Lobo's disease and lepromatous leprosy- A comparative study.

Article Synopsis
- Both Jorge Lobo's disease (JLD) and lepromatous leprosy (LL) have common features such as a weakened cellular immune response, primarily due to macrophage dysfunction, impacting disease maintenance.
- The study compared macrophage subtypes in skin lesions from JLD patients and LL samples, using specific markers to identify different macrophage responses, revealing no significant density differences in certain markers, but higher resident macrophages in LL.
- Findings indicate that both diseases have a dominant M2 (anti-inflammatory) response with notable amounts of iNOS+ macrophages, suggesting impaired immune function similar to M2 macrophages that limits effective pathogen eradication.
Intra-population variability of the saccular, utricular and lagenar otoliths of the garfish Belone belone (Linnaeus, 1760) from South-Western Ionian Sea (Central Mediterranean Sea).

The garfish Belone belone represents the only valid endemic Belone species for the Mediterranean Sea and the eastern Atlantic Ocean. It shows a wide global distribution range, with a high commercial value and ecological relevance in the pelagic domain. Despite this, there needs to be more knowledge regarding the otoliths of this species, with the total absence of descriptions regarding asterisci and lapilli from Mediterranean populations and a lack of studies on the reliability of shape analysis on its sagittae.

This study provides the fatty acid profile, presence of Omega 3 fatty acids (ω3FAs) and therapeutic potential of the skin of Garfish (), a highly nutritious fish. The ω3FAs were obtained using the urea crystallization method and confirmed by UV VIS spectroscopy, HPLC, FT-IR, and NMR. Additionally, the therapeutic potential of the ω3FAs was assessed through antioxidant, antimicrobial, antibiofilm, and toxicity assays.
