La prohibición de asistencia financiera en las sociedades de capital: su incumplimiento a la luz de la actual jurisprudencia en España
Authors: De Vivero de Porras Carmen 
Published: November 2024

La prohibición de asistencia financiera por parte de las sociedades de capital a un tercero para adquirir sus propias acciones o participaciones (así como de otra sociedad del grupo o dominante) contenida en los artículos 143.2 y 150.1 ambos de la LSC, ha dado lugar a muy diversos pronunciamientos judiciales. La casuística con la que nos encontramos diariamente es diversa y plural, con lo que en numerosas ocasiones se antoja complicado proteger adecuadamente los intereses en juego a la vista de los negocios a los que puede afectar la asistencia prohibida. En los últimos años, se ha impuesto por el Tribunal Supremo en España, una interpretación restrictiva de la nulidad, así como —declarada la misma— si esta puede o debe contagiar a otros negocios e incluso a la propia adquisición que el Tribunal Supremo niega. En el presente trabajo se lleva a cabo un análisis de la doctrina del Alto Tribunal y de la extensión o no de la nulidad de la asistencia prohibida, al negocio de adquisición de las acciones o participaciones propias, partiendo de la finalidad patrimonial o financiera (en la que se basa el alto Tribunal) y/o del régimen de control que esa asistencia puede otorgar en la sociedad a quien la obtiene.

HIGHLIGHTS

Clinicopathologic characteristic of patient with LEEP procedures dominated by women above 35 years old, with total parity less than 3 and without history of contraceptive usage.
The p16 expression analyzed by immunohistochemistry technique. The positive and negative reactivity of p16 ratio was 3:5 on LEEP specimen which microscopically appear as chronic cervicitis, low-grade and high-grade squamous intraepithelial lesion.

ABSTRACT
Objective: The study aim was to reveal p16 expression with the clinicopathological characteristics of patients who underwent cervical biopsy using the Loop electrosurgical procedure (LEEP) at Udayana University Hospital for the period 2020 – 2023.
Materials and Methods: The research was conducted at Anatomic Pathology Laboratory of Udayana University Hospital, Denpasar, Bali, Indonesia. The samples were selected based on inclusion criteria such as the formalin fixed paraffin embedded (FFPE) sample from positive IVA patient and continue for LEEP procedure. Otherwise, the exclusion criteria were moldy FFPE sample and incomplete clinical data. Then, p16 immunostaining procedure was carried out manually. The interpretation of p16 results was analyzed using SPSS software, version 25 by International Business Machines (IBM) Corporation.
Results: The positive p16 expression was revealed in 12 samples (38.7%), in contrast the negative staining appeared in 19 samples (61.3%). Unfortunately, p16 expression was not significant statistically based on age, parity, and contraceptive history, with p-values of 1.00, 0.45, and 0.65, respectively. Meanwhile, a statistically significant association was found between p16 expression and histopathologic diagnostic (p = 0.02, 95% CI 1.4 – 38.3). In addition, 22.2% of the variation of p16 expression based on multivariate analysis demonstrating a significant correlation (p = 0.01).
Conclusion: p16 expression with histopathology diagnostic characteristic in patient who underwent Loop Electrosurgical Excision Procedure (LEEP) was found statistically significant. Moreover, clinical application of p16 in daily practice should be performed with consideration especially for pre-cancer lesion in LEEP biopsy specimen procedure and clinicopathological approach is essential.

HIGHLIGHTS

Pathogenesis of cervical elongation is still limited, including the histological and molecular differences between a cervical elongation and a normal cervix.
The expression of collagen-1 level in the cervical elongation group was stronger compared to the cervical elongation with POP and control group.

ABSTRACT
Objective: This study aimed to assess differences in the expression of Collagen-1 and Elastin in cervical tissues among patients with Cervical Elongation (CE), Pelvic Organ Prolapse (POP), a combination of CE with POP, and those without either condition.
Materials and Methods: An analytical study with a cross-sectional design was conducted, using immunohistochemistry (IHC) to analyze cervical tissue samples preserved in paraffin blocks. Patient groups included those diagnosed with CE, POP, CE combined with POP, and a control group without CE or POP. All participants underwent surgery between January 2021 and April 2023. IHC was used to measure the expression levels of Collagen-1 and Elastin in each tissue sample. Observations were made under 400x magnification, focusing on five randomly selected visual-field areas in each sample to determine the area fraction. Two experienced pathologists conducted the analyses in a blinded manner to ensure objective evaluation.
Results: Statistical analysis using the Kruskal-Wallis test revealed significant differences in the expression of Collagen-1 across the four groups (CE, POP, CE with POP, and control). Patients with CE showed a higher expression of Collagen-1 than those with CE and POP combined, as well as the control group. However, no significant differences in Elastin expression were observed among the groups.
Conclusion: Collagen-1 expression differs significantly across patients with CE, POP, and CE combined with POP, suggesting a distinct role in cervical tissue remodeling in these conditions. Conversely, Elastin expression was consistent across all groups, indicating that it may not play a differentiating role in these pathologies. These findings highlight Collagen-1’s potential involvement in the structural changes associated with CE and POP.

Kemajuan sektor pertanian suatu negara dapat dilihat dari kesejahteraan petaninya. Nilai Tukar Petani (NTP) dapat dijadikan indikator dari kesejahteraan petani. NTP merupakan rasio antara indeks harga yang diterima petani (Id) dan indeks harga yang dibayarkan petani (Ib) sehingga diharapkan dari waktu ke waktu nilainya terus mengalami kenaikan. NTP dapat digunakan sebagai bahan pertimbangan dalam penentuan kebijakan untuk mengembangkan sektor pertanian di Indonesia. Oleh karena itu, diperlukan peramalan NTP. Penelitian ini bertujuan untuk meramalkan NTP di Indonesia menggunakan metode hibrida Singular Spectrum Analysis (SSA) - Seasonal Autoregressive Integrated Moving Average (SARIMA). Data yang digunakan adalah data NTP dari bulan Januari 2008 hingga Desember 2022 di Indonesia. Metode yang digunakan yaitu hibrida SSA-SARIMA. SSA mendekomposisikan data NTP kedalam komponen tren dan noise. SARIMA digunakan untuk memodelkan komponen noise. Peramalan metode hibrida SSA-SARIMA didapatkan dengan menjumlahkan hasil peramalan SSA dan hasil peramalan komponen noise model SARIMA. Hasil penelitian menunjukkan bahwa metode hibrida SSA dengan window length ­sebesar 84 dan model SARIMA didapatkan nilai MAPE sebesar 1,429%. Metode hibrida SSA-SARIMA dapat meramalkan NTP dengan baik. Hasil peramalan NTP pada periode Januari – Maret 2023 berturut-turut yaitu 110,477; 110,132; dan 109,936 yang artinya petani sejahtera karena nilai NTP lebih dari 100.The progress of a country's agricultural sector can be seen from the welfare of its farmers. Farmers' Terms of Trade (FTT) can be used as an indicator of farmer welfare. FTT is the ratio between the price index received by farmers (Id) and the price index paid by farmers (Ib) so it is expected that from time to time its value will continue to increase. FTT can be used as material for consideration in determining policies to develop the agricultural sector in Indonesia. Therefore, it is necessary to forecast FTT. This study aims to predict FTT in Indonesia using the Singular Spectrum Analysis (SSA) - Seasonal Autoregressive Integrated Moving Average (SARIMA) hybrid method. The data used is FTT data from January 2008 to December 2022 in Indonesia. The method used is SSA-SARIMA hybrid. SSA decomposes NTP data into trend and noise components. SARIMA is used to model the noise component. Forecasting of the SSA-SARIMA hybrid method is obtained by summing the results of the forecasting of the SSA and the forecasting results of the noise component of the SARIMA model. The results showed that the SSA hybrid method with a window length of 84 and the SARIMA model obtained a MAPE value of 1.429%. The SSA-SARIMA hybrid method can predict FTT well. The FTT forecasting results for the January – March 2023 period are 110,477; 110,132; and 109,936, which means farmers are prosperous because the FTT value is more than 100.
