description: This paper examined the impact of the real effective exchange rate variations on the overall balance of payments in Nigeria between 1986-2019. The autoregressive distributed lag (ARDL) bounds cointegration technique was used to analyse the data based on the outcome of the stationarity test. The bounds test indicated a long-run relationship among the macroeconomic variables in the balance of payments function. Empirical evidences indicated that real exchange rate had insignificant negative effect on the balance of payments in the long-run, but exerted significant positive effect in the short-run with a lag. Private sector credit impacted negatively in the long-run, while real output significantly improved balance of payments both in the long-run and in the shortrun with a lag. Lagged real interest rate and oil prices had significant positive short-run impacts, while the latter impacted negatively in the long-run. Overall, the result implied that real exchange rate depreciation may not be used to improve Nigeria’s balance of payments position. The study, therefore, recommended that the monetary authority should adopt proactive export promotion policies that will strengthen and stabilise the real exchange rate of the naira. It is also important to ensure productive utilization of the private sector credits, and diversify the country away from the oil sector in view of the current global dwindling oil prices.

description: The increasing incidence of obesity, leading to metabolic complications is now recognized as a major public health problem. The adipocytes are not merely energystoring cells, but they play crucial roles in the development of the so-called metabolic syndrome and cardiovascular diseases due to the adipocyte-derived bioactive factors, such adipokines, cytokines and growth factors [1]. Most of adipokines, which affect whole-body homeostasis, are pro-inflammatory, whereas a small number of anti-inflammatory adipokines, including adiponectin exert beneficial actions on obese complications. The dysregulated production and secretion of adipokines seen in obesity is linked to the pathogenesis of various disease processes [2]. New emerging data showed that melatonin, pineal gland indoleamine, play an important role in body weight regulation and energy metabolism [3]. Lean and obese mice (ob/ob) received melatonin (100 mg/kg/day) or vehicle in drinking water for 8 weeks. In obese mice we observed a significant increase in fat depots and a deregulation of adipokines and cytokines fat expressions. In particular, we observed a significant reduction of adiponectin and an increase of resistin and visfatin at adipose tissue level. Melatonin administration for 8 weeks reduced fat accumulation and restored the correct adipokines expression, modulating in turn the vascular tone and homeostasis. These results indicate that melatonin counteracts some of the disrupting effects of obesity.

Subjects: Obesity; melatonin; mitochondria; proximal convoluted tubules.

description: Obesity is a common and complex health problem, which impacts crucial organs; it is also considered an independent risk factor for chronic kidney disease [1]. Few studies have analyzed the consequence of obesity in the renal proximal convoluted tubules, the major section of the reabsorptive process. To best perform its functions, the kidney requires energy primarily provided by mitochondria. Melatonin, indoleamine and antioxidant, has been identified in mitochondria, and overwhelming evidence has documented its essential role in the prevention of oxidative mitochondrial damage [2]. Herein, we evaluated the mechanism(s) of mitochondrial alterations in an animal model of obesity (ob/ob mice) and describe the beneficial effects of melatonin treatment on mitochondria morphology and dynamics as influenced by mitofusin- 2 and the intrinsic apoptotic cascade. Melatonin was dissolved in 1% ethanol and added to the drinking water from postnatal week 5 to 13; the calculated dose of melatonin intake was 100 mg/kg body weight/day. Compared to control mice, obesity-induced morphological alterations were apparent in the proximal tubules; the tubules contained round mitochondria with irregular, short cristae and the lining cells excited and elevated apoptotic index. Melatonin supplementation in obese mice changed mitochondria shape and cristae organization of proximal tubules, enhanced mitofusin-2 expression, which in turn modulated the progression of the mitochondria- driven intrinsic apoptotic pathway. The results aid in reducing renal failure. The melatonin-mediated changes probably suggest the use of melatonin to protect against renal morphological damage and dysfunction during metabolic disease.

description: The newly developed "void expansion method" allows for an efficient generation of porous packings of spherical particles over a wide range of volume fractions using the discrete element method. Particles are randomly placed under addition of much smaller "void-particles". Then, the void-particle radius is increased repeatedly, thereby rearranging the structural particles until formation of a dense particle packing. The structural particles' mean coordination number was used to characterize the evolving microstructures. At some void radius, a transition from an initially low to a higher mean coordination number is found, which was used to characterize the influence of the various simulation parameters. For structural and void-particle stiffnesses of the same order of magnitude, the transition is found at constant total volume fraction slightly below the random close packing limit. For decreasing void-particle stiffness the transition is shifted towards a smaller void-particle radius and becomes smoother.

description: In the last years metal nanoparticles has seen an escalation as new multi-functional platform for diagnostic and drug delivery, but, at the same time, awareness towards their impact on human and environmental health requires studies that characterize their potential cytotoxic effects (Dykman and Khlebtsov, 2012). In this work we investigate uptake and toxicity of gold nanoparticles (Au NPs) towards cells of the human vascular system (Human Umbilical Vein Endothelial Cells, HUVEC), because these are the first one to get in contact with NPs intravenously administered. The characterization of Au NPs is done by standard methods and by Two-Photon Fluorescence Correlation Spectroscopy. Au NPs uptake is investigated through transmission electron microscopy, fluorescence microscopy and ICPAES, and NPs toxicity is measured through standard bio-analytical tests. We have explored the cytotoxicity of Au NPs by evaluation of gene expression of inflammatory markers and by the cell production of reactive oxygen species (ROS) after incubation with Au NPs. In parallel, we propose and study a new in vitro model system, which consists in a linear microfluidic device (MFD) in polydimethylsiloxane. In this model we add shear stress associated with a flowing medium and a continuous infusion of Au NPs solution, since these phenomena are present when NPs are intravenously administrated (Mahto et al., 2010). The comparison between static and flow conditions shows that administration of equal concentrations of Au NPs under flow results in reduced sedimentation and uptake of NPs on the cells and in 20% lower cytotoxicity, providing new useful information to evaluate the therapeutic efficacy of nanoparticle-based formulations.

description: Among the 21 Herbig Ae/Be stars studied, new detections of a magnetic field were achieved in six stars. For three Herbig Ae/Be stars, we confirm previous magnetic field detections. The largest longitudinal magnetic field, = -454+-42G, was detected in the Herbig Ae/Be star HD101412 using hydrogen lines. No field detection at a significance level of 3sigma was achieved in stars with debris disks. Our study does not indicate any correlation of the strength of the longitudinal magnetic field with disk orientation, disk geometry, or the presence of a companion. We also do not see any simple dependence on the mass-accretion rate. However, it is likely that the range of observed field values qualitatively supports the expectations from magnetospheric accretion models giving support for dipole-like field geometries. Both the magnetic field strength and the X-ray emission show hints for a decline with age in the range of ~2-14Myrs probed by our sample supporting a dynamo mechanism that decays with age. However, our study of rotation does not show any obvious trend of the strength of the longitudinal magnetic field with rotation period. Furthermore, the stars seem to obey the universal power-law relation between magnetic flux and X-ray luminosity established for the Sun and main-sequence active dwarf stars.

description: DRC has expressed interest in joining the EAC regional bloc to tap into the benefits of the regional trade and expanded markets. Using trend analysis of trade flows and SMART-WITS Partial Equilibrium model, this study examines the likely impact of DRC’s membership in the EAC, to establish trade effects of liberalising trade between EAC and DRC. The emerging results reveal that trade effects are positive among the EAC partner states, more so for Rwanda and Uganda given that there are the leading EAC exporters to DRC. The analysis also identifies the EAC main economic sectors poised to benefit a result of this trade liberalisation. At a sectoral level, the largest trade effects will be experienced in agro-processing, metal products and mineral ores industries. These findings point to the need for EAC members to pursue develop these sectors while pursuing industrialization agenda to replace DRC’s imports from the rest of the world.

description: Facial asymmetry is normal in humans[1]. Authors indicated that facial asymmetry could influence the shape and function of the temporomandibular joints and vice versa[2]. In this study we collected preliminary reference values for facial asymmetry in adults with temporomandibular disorders (TMD), compared to a control group, using a 3D stereophotogrammetric imaging system and electromyographic (EMG) indices. Forty subjects (22 TMD; 18 control; paired for age: 21±2y) were recruited. Five linear measurements for each hemiface and asymmetry index (AI%) were computed from stereophotogrammetric scans. Standardized EMG indices for masseter and temporal muscles were obtained during clenching and gum chewing. Means of control and TMD groups were compared by t-test. For both groups, the AI for all linear measurements ranged from -10% to +10%; there was a great variability, especially for TMD group, who showed the higher values. For EMG indices, TMD group demonstrated a tendency to a more asymmetric muscular recruitment in static activities (masseter & temporal symmetry, C 87.5±1.76%; TMD 84.6±6.2%; p=0.06) and reduced symmetry during gum chewing (C 67.1± 20.9%; TMD 55.0±18.1%; p=0.06). The presence of higher asymmetry for stereophotogrammetry and EMG analyses, as well as the presence of alterations of masticatory function for the TMD group, suggest that this relationship should be further investigated. An analysis with a larger sample and with more severe TMD patients, together with a longitudinal study, is required to understand these possible relationships between morphology and function.

description: Families of three- and four-point corrector formulae are derived, which differ from standard formulae in that they express yո in terms of more than one previously computed ordinate. It is shown that the standard formulae are special cases of the more general formulae derived here. By theoretical argument and by numerical experiments it is shown that the standard formulae are often inferior to others which are developed in this thesis. The three-point family, with its associated truncation error, is given in (7) and (9) of Chapter 2 on page 12. The four-point family is given in (41) on page 25. With the help of Rutishauser's method each family is examined for stability. In the four-point case a procedure is described, whereby the magnitude of the coefficient in the error term can be minimized subject to the restriction that the formula shall remain stable. Also a theorem is proved, which states that no stable four-point formula can have a truncation error of degree higher than fifth in the step-size h.
Effect of PTH (1-34) on trabecular bone of rat vertebral body in induced-biochemical osteoporosis by calciumdeprived diet

description: Rats fed calcium-deprived diet were used as experimental model for studying bone modelling alterations during biochemical osteoporosis and recovery of bone loss. Such model is suitable to evaluate the possible effects exerted by PTH(1-34) in preventing as well as in recovering metabolic osteoporosis. Three-month-old Sprague Dawley male rats were divided in different groups: some fed normal diet or calcium- deprived diet with/without 40μg/Kg/day PTH(1-34), provided by Eli Lilly-USA, for 4 weeks and some with restoration of normal diet with/without PTH (1-34) for further 4 weeks. To evaluate the occurrence of osteogenesis during the first 4 weeks of the experimental period, rats received three labels of bone deposition at 1st, 20th and 27th day (and then were sacrificed); during the successive 4 weeks (in which those rats previously fed with calcium-deprived diet had restoration of normal diet), animals received three labels of bone deposition at 1st, 7th and 14th day. Histomorphometrical analyses were performed on cortical and trabecular bone taken from the central level of the 5th lumbar vertebral body, transversely sectioned. The results showed that differences among the groups were observed mainly in trabecular bone with respect to cortical one, thus underlining the different role of the two types of bone architecture in mineral and skeletal homeostasis. Concerning trabecular bone, the observations showed that administration of PTH (1-34) during calcium-deprived diet and/or during the restoration of normal diet induces higher deposition of trabecular bone with respect to that recorded in rats that never received PTH(1-34), neither during calcium-deprived diet nor during restoration of normal diet. Since increments of trabecular bone are detectable only after the period of diet restoration (but not before), the authors suggest that a chronic administration of PTH (1-34) is necessary to achieve appreciable results on bone mass recovery.

description: The primary aim was to assess the effectiveness and safety of three different algorithms of using steroids and inner ear catheter (INCAT) MED-EL® in partial deafness patients who underwent cochlear implantation. The secondary goal was the assessment of the impact of the depth of INCAT on hearing preservation after cochlear implantation. There were three algorithms of steroid administration: 1) methylprednisolone 62.5 mg/ml (solution), 3 patients; 2) methylprednisolone 40 mg/ml (suspension), 4 patients; 3) dexamethasone 4 mg/ml (solution), 3 patients. Pure tone audiometry (0.125–8 kHz) was performed preoperatively, 1 and 6 months post-op. Hearing preservation was assessed according to the HEARRING group formula. Impedance measurements were taken at two days, 1 and 6 months after surgery. Patients treated with methylprednisolone 40 mg/ml in suspension showed the best hearing preservation (50% complete and 50% partial preservation) 1 month post-op and later remained the most favorable. The lowest impedance was found in this group both 1 and 6 months post-op. A shorter INCAT insertion depth appeared to be more favorable than a longer one. Our results suggest that patients treated with methylprednisolone 40 mg/ml (suspension) had better hearing outcomes compared to the other two medications.

description: A number of plastic events were described in the spinal cord in the course of amyotrophic lateral sclerosis (ALS). These consist of various morphological effects, involving neurons, glia, and inflammatory cells, as well. Among plastic changes, an increase in neuronal progenitor cells (NPC) occurs within ependymal cells layer of lamina X. This stem cell-like activity is known to be weak in baseline conditions but it is known to increase significantly during spinal cord disorders, when it preferentially generates glial cells, due to the strong gliogenic effect of the spinal cord “milieu”. In the present work, we used immunohistochemistry and electron microscopy to analyze cell number within lamina X at the end stage of disease in the G93A mouse model of ALS in baseline conditions and following chronic lithium administration. These cells were identified by using GFAP, bIII-tubulin, NeuN, and calbindin- D28K immunostaining. In the absence of lithium we observed an increase of lamina X cells in ALS mice with a glial phenotype, while in G93A mice treated with lithium these cells differentiate towards neuronal-like phenotype. These effects of lithium are concomitant with slowed disease progression and are reminiscent of the neurogenetic effects described in the sub-ependymal ventricular zone of the hippocampus. The present data confirm the scarce NPC activity in the intact spinal cord which is enhanced by disease conditions; in the presence of chronic lithium, such increased NPCs differentiate towards a neuron-like rather than a glial phenotype.

description: The classic region-specific characterization of various neurodegenerative disorders and acute neurological insults has been challenged by recent studies showing multiple brain areas and peripheral sites in addition to those specifically described as disease- specific. In this presentation we will shortly overview the multiple brain regions, whichh according to various time-dependent progression are recruited in specific neurodegenerative disorders. Detailed anatomical studies analyzing the fine connections of specific brain areas are key to understand site-specificity of disease spreading. Molecular mechanisms involving disease-specific different misfolded proteins help to explain the variety of these disorders at disease onset, while similar cell-tocell protein spreading helps to understand why the neuroanatomical pattern of each disease partly overlaps at the end stages. Experimental evidence from our lab will be reported to study cell-to-cell spreading of misfolded protein working as the molecular engine which fosters disease progression along well defined anatomical connections. Biochemical properties of specific misfolded proteins will be compared in order to understand the severity of disease course along various anatomical areas.

On the Herman-Kluk Semiclassical Approximation

description: For a subquadratic symbol $H$ on $\R^d\times\R^d = T^*(\R^d)$, the quantum propagator of the time dependent Schrödinger equation $i\hbar\frac{\partialψ}{\partial t} = \hat Hψ$ is a Semiclassical Fourier-Integral Operator when $\hat H=H(x,\hbar D_x)$ ($\hbar$-Weyl quantization of $H$). Its Schwartz kernel is describe by a quadratic phase and an amplitude. At every time $t$, when $\hbar$ is small, it is "essentially supported" in a neighborhood of the graph of the classical flow generated by $H$, with a full uniform asymptotic expansion in $\hbar$ for the amplitude. In this paper our goal is to revisit this well known and fondamental result with emphasis on the flexibility for the choice of a quadratic complex phase function and on global $L^2$ estimates when $\hbar$ is small and time $t$ is large. One of the simplest choice of the phase is known in chemical physics as Herman-Kluk formula. Moreover we prove that the semiclassical expansion for the propagator is valid for $| t| << \frac{1}{4δ}|\log\hbar|$ where $δ>0$ is a stability parameter for the classical system.

description: Recently, tissue engineering has merged with stem cell technology to develop new sources of transplantable material for injury or disease treatment. Eminently interesting, are bone and joint injuries/disorders because of the low self-regenerating capacity of the matrix secreting cells, particularly chondrocytes (1). Gelatin based scaffolds are considered to be a highly suitable 3D material for tissue regeneration, due to high biocompatibility and adaptation to native tissues. In the present study, the chondrogenic and osteogenic potential of a porous gelatin based scaffold (2), alone or in combination with hydroxyapatite crystals, was investigated in human mesenchymal stem cells. Cells were culture up to 4 weeks on the scaffold and on monolayer. MTT assay was performed to evaluate cell viability, light and transmission electron microscopy were carried out to demonstrate cell colonization inside the porous architecture of the biomaterial and scaffold adhesion. The expression of chondrogenic markers such as SOX9, collagen type II, aggregan and versican and osteogenic markers such as Collagen type I, Runx -2, osteopontin and bone matrix protein, were investigated by Real Time PCR. Results showed an high cell viability, adhesion and colonization of the scaffold. Real Time PCR data demonstrated an up-regulation of all the chondrogenic and osteogenic markers analyzed. In conclusion, gelatin porous scaffold provides an improved environment for chondrogenic and osteogenic differentiation of stem cells compared to cell monolayer culture system.

description: Nucleic acid-based therapeutics have become a key pillar of the ‘third wave’ of modern medicine, following the eras of small molecule inhibitors and antibody drugs. Their rapid progress is heavily dependent on delivery technologies, with the development of N-acetylgalactosamine (GalNAc) conjugates marking a breakthrough in targeting liver diseases. This technology has gained significant attention for its role in addressing chronic conditions like chronic hepatitis B (CHB) and nonalcoholic steatohepatitis (NASH), which are challenging to treat with conventional methods. This review explores the origins, mechanisms, and advantages of GalNAc-siRNA delivery systems, highlighting their ability to target hepatocytes via the asialoglycoprotein receptor (ASGPR). The literature reviewed covers preclinical and clinical advancements, particularly in CHB and NASH. Key developments in stabilization chemistry and conjugation technologies are examined, emphasizing their impact on enhancing therapeutic efficacy and patient compliance. GalNAc-siRNA technology represents a transformative advancement in RNA interference (RNAi) therapies, addressing unmet needs in liver-targeted diseases. While significant progress has been made, challenges remain, including restricted targeting scope and scalability concerns. Continued innovation is expected to expand applications, improve delivery efficiency, and overcome limitations, establishing GalNAc-siRNA as a cornerstone for future nucleic acid-based treatments.

The role of disc self-gravity in the formation of protostars and protostellar discs

description: We use time-dependent, one-dimensional disc models to investigate the evolution of protostellar discs that form through the collapse of molecular cloud cores and in which the primary transport mechanism is self-gravity. We assume that these discs settle into a state of thermal equilibrium with Q = 2 and that the strength of the angular momentum transport is set by the cooling rate of the disc. The results suggest that these discs will attain a quasi-steady state that persists for a number of free-fall times and in which most of the mass within 100 au is located inside 10-20 au. This pile-up of mass in the inner disc could result in temperatures that are high enough for the growth of MHD turbulence which could rapidly drain the inner disc and lead to FU Orionis-like outbursts. In all our simulations, the inner regions of the discs (r < 40 au) were stable against fragmentation, while fragmentation was possible in the outer regions (r > 40 au) of discs that formed from cores that had enough initial angular momentum to deposit sufficient mass in these outer regions. The large amounts of mass in these outer regions, however, suggests that fragmentation will lead to the formation of sub-stellar and stellar mass companions, rather than planetary mass objects. Although mass accretion rates were largely consistent with observations, the large disc masses suggest that an additional transport mechanism (such as MRI occuring in the upper layers of the disc) must operate in order to drain the remaining disc material within observed disc lifetimes.

description: We examine the influence of nebular continuous and line emission in high redshift star forming galaxies on determinations of their age, formation redshift and other properties from SED fits. We include nebular emission consistently with the stellar emission in our SED fitting tool and analyse differentially a sample of 10 z~6 galaxies in the GOODS-S field studied earlier by Eyles et al. (2007). We find that the apparent Balmer/4000 Ang breaks observed in a number of z~6 galaxies detected at >~3.6 micron with IRAC/Spitzer can be mimicked by the presence of strong restframe optical emission lines, implying in particular younger ages than previously thought. Applying these models to the small sample of z~6 galaxies, we find that this effect may lead to a typical downward revision of their stellar ages by a factor ~3. In consequence their average formation redshift may drastically be reduced, and these objects may not have contributed to cosmic reionisation at z>6. Extinction and stellar mass estimates may also be somewhat modified, but to a lesser extent. Careful SED fits including nebular emission and treating properly uncertainties and degeneracies are necessary for more accurate determinations of the physical parameters of high-z galaxies.

description: We consider a system of nonlinear wave equations with constraints that arises from the Einstein equations of general relativity and describes the geometry of the so-called Gowdy symmetric spacetimes on T3. We introduce two numerical methods, which are based on pseudo-spectral approximation. The first approach relies on marching in the future time-like direction and toward the coordinate singularity t=0. The second approach is designed from asymptotic formulas that are available near this singularity; it evolves the solutions in the past timelike direction from "final" data given at t=0. This backward method relies a novel nonlinear transformation, which allows us to reduce the nonlinear source terms to simple quadratic products of the unknown variables. Numerical experiments are presented in various regimes, including cases where "spiky" structures are observed as the coordinate singularity is approached. The proposed backward strategy leads to a robust numerical method which allows us to accurately simulate the long-time behavior of a large class of Gowdy spacetimes.

description: The primary aim was to assess the effectiveness and safety of three different algorithms of using steroids and inner ear catheter (INCAT) Medel® in partial deafness patients who underwent cochlear implantation. The secondary goal was the assessment of the impact of the depth of INCAT on hearing preservation after cochlear implantation. There were three algorithms of steroid administration: 1) methylprednisolone 62.5 mg/ml (solution), 3 patients; 2) methylprednisolone 40 mg/ml (suspension), 4 patients; 3) dexamethasone 4 mg/ml (solution), 3 patients. Pure tone audiometry (0.125–8 kHz) was performed preoperatively, 1 and 6 months post-op. Hearing preservation was assessed according to the HEARRING group formula. Impedance measurements were taken at two days, 1 and 6 months after surgery. Patients treated with methylprednisolone 40 mg/ml in suspension showed the best hearing preservation (50% complete and 50% partial preservation) 1 month post-op and later remained the most favorable. The lowest impedance was found in this group both 1 and 6 months post-op. A shorter INCAT insertion depth appeared to be more favorable than a longer one. Our results suggest that patients treated with methylprednisolone 40 mg/ml (suspension) had better hearing outcomes compared to the other two medications.

description: The set $\mathscr{F}(2;2)$ of quadratic foliations on the complex projective plane can be identified with a \textsc{Zariski}'s open set of a projective space of dimension 14 on which acts $\mathrm{Aut}(\mathbb{P}^2(\mathbb{C})).$ We classify, up to automorphisms of $\mathbb{P}^2(\mathbb{C}),$ quadratic foliations with only one singularity. There are only four such foliations up to conjugacy; whereas three of them have a dynamic which can be easily described the dynamic of the fourth is still mysterious. This classification also allows us to describe the action of $\mathrm{Aut}(\mathbb{P}^2(\mathbb{C}))$ on $\mathscr{F}(2;2).$ On the one hand we show that the dimension of the orbits is more than 6 and that there are exactly two orbits of dimension $6;$ on the other hand we obtain that the closure of the generic orbit in $\mathscr{F} (2;2)$ contains at least seven orbits of dimension~7 and exactly one orbit of dimension $6.$

description: Let A and B be n-square complex matrices with eigenvalues λ₁, λ₂,… λn and μ₁, μ₂,…μn respectively. The matrices A and B are said to have property L if any linear combination aA + bB, with a, b complex, has as eigenvalues the numbers aλᵢ + bμᵢ, i = 1,2, …,n. A theorem of Dr. M. D. Marcus, which gives a necessary and sufficient condition such that two matrices A and B have property L in terms of the traces of various power-products of A and B, is proved. This theorem is used to investigate the conditions on B for the special cases n = 2, 3, and 4, when A is in Jordan canonical form. The final result is a theorem which gives a necessary condition on B for A and B to have property L when A is in Jordan canonical form.
